Tungsten Catalyst

Tungsten Catalyst an overview Weison Advanced Materials

In recent years, there has been a rising interest in tungsten catalyst due to their properties as well as wide probable applications. This kind of materials displays exclusive acidity that recovers the activity along with selectivity, chemical as well as thermal stability and environmental protection, thus being regarded as a kind of promising catalyst owing to its resourceful application, including the metathesis and isomerization of alkenes.

Introduction to purest Tungsten Catalyst

Pristine tungsten catalyst principally includes tungsten trioxide, tungsten acid, tungsten carbide, etc. Recently, an immense deal of research based on pristine tungsten catalysts was focused on various green catalytic oxidation reactions, which showcased excellent catalytic performance as well as chemical stability.

The tungsten-based catalyst can be applied to the photo catalytic oxidation reaction, particularly tungsten trioxide. Tungsten trioxide, with a band gap between 2.4 along with 2.8鈥唀V, is a observable light response catalyst with constancy in acidic reaction conditions.

The color of tungsten catalyst is bright gray and the appearance of tungsten catalyst is polyhedron granule. Tungsten catalyst is used extensively, not only used as flux in the analysis of carbon and sulfur, also as accelerator in the processing. High purity tungsten particles catalyst is also essential in the analysis of the infrared carbon and sulfur reagents, tungsten particles of the world amounted to tens of tons.

Processing of tungsten catalyst

Pure tungsten granulate as tungsten catalyst is very easy for processing because it is quite pliant and can contain small amounts of oxygen and carbon. Since the properties of pure tungsten granule allow the use of purest tungsten for great purposes. The purity of tungsten particle can reach 99.90% or 99.95% min. However, 99.90% of purity is not enough for materials. Thus, carbon - not more than 0.001% and sulfur - not more than 0.0005% are used to achieve better stability. Clean and pure tungsten granule is much needed to play a good role of catalyst in the material production. So, in between 99.95% to 99.99% of purity is important to use during material production and amplify its applications such as carbon sulfur analysis , induction accelerator , radiation shielding filler and so forth.

We at Weison Advanced Materials aim to provide a complete description of the recent advances in the field of tungsten-containing heterogeneous catalyst for green catalytic oxidation process. Though significant advances have been accomplished in the development of the tungsten-containing heterogeneous catalyst in green catalytic oxidation procedure, there is rarely relevant review focusing on the aspect. Hence, this is our main driving force to give to the fundamental exemplifications in this field.

Choosing the Right Tungsten Carbide Ball Material for Aggressive Environments

Tungsten carbide is a homogenous mixture of tungsten carbide grains in a binder matrix, with cobalt being the most commonly used binder matrix. The tungsten carbide grains are fused into a solid matrix of cobalt metals under extreme heat and pressure in a process called sintering. There are many different grades of tungsten carbide balls available, making it possible to provide carbide balls that are tailored for most any application. In general, a higher percentage of cobalt will provide a tougher but softer grade while a lower percentage of cobalt will provide a harder but less tough grade.

The hardness of tungsten carbide ball is evidenced by the fact that it is commonly used for tools used to cut steel and other materials, and for armor piercing ammunition. Its abrasion resistance and resistance to shock are both excellent. Tungsten carbide balls are also practically inert so it is able to resist corrosion in nearly any environment. But it should be noted that bases with a pH below 4 have a tendency to attack the binder. Tungsten carbide ball is also one of the most costly ball materials.

Naturally, tungsten carbide balls are used in applications where extreme hardness and wear resistance are required. Tungsten carbide balls are used in heavy machinery applications because of their wear resistance and strength. They are frequently used in the down-hole tool industry for hard banding, which refers to covering the outer surface of the lower portion of a tool with a wear material to enhance its life. Other common applications for tungsten carbide balls include ball screws, bearings, valves, flow meters, pivots, detents and tips.

Why Use Pure Tungsten Carbide over Other Materials

Tungsten Carbide (WC) is an inorganic chemical compound containing equal parts of pure tungsten and carbon atoms. Tungsten carbide in its most basic form is a fine grey powder, but can be processed and formed into shapes for use in industrial machinery, tools, abrasives, as well as in jewelry products.

Tungsten carbide is approximately three times more rigidity than steel, with a Young modulus of approximately 550GPa, and is much denser than steel or titanium. It is comparable with corundum in hardness and can only be polished and finished with abrasives of superior hardness such as silicon carbide, cubic boron nitride and diamond amongst others, in the form of powder, wheels and compounds.

Pure Tungsten Carbide is an incredibly versatile material that comes in numerous different types to give varying properties. These varying characteristics are the main reason for its popularity in a range of applications and industries. Tungsten carbide falls between 8.5 and 9.0 on Moh hardness scale, making it almost as hard as diamond.

How is the Pure Tungsten Carbide Formed?

In typical conditions, when uncombined, Tungsten is a steel-grey colored metal. Tungsten is only found naturally on earth when combined in chemical compounds. It was first discovered in 1781 and the free element got its reputation for its tough physical properties, particularly the fact that it has the highest melting point of non-alloyed metals and the second highest of all the elements a behind carbon.

Tungsten carbide is formed by reacting carbon and tungsten at temperatures of between 1400 and 20000C. These high temperatures make it ideal to be for mills and cutting tools for industrial use which are able to required heavy use and high temperatures. Tungsten carbide starts off as a fine grey powder, in this form its hard wearing properties makes for an excellent abrasive or this powder can be pressed and formed into a desired shape, for example tools, jewelry and machinery. The rare and extraordinary physical properties retained by Tungsten carbide makes it useful for a variety of applications.

It is enormously strong and wear-resistant, so much so that there are only a scarce number of materials on earth that can cut or scratch tungsten carbide with industrial diamond abrasives being one. It is important to understand that tungsten carbide is available in different grades with varying properties depending on use. There are many different grades of tungsten carbide nowadays available in the market for sale which varies on just a few parameters: grain size, hardness and the degree to which a binder is used.

How Much Strength Does Tungsten Carbide Offer?

Minimum Transverse Rupture Strength (TRS)

The transverse rupture strength of tungsten carbide with cobalt variations is sometimes regarded as an indication of toughness which increases as hardness decreases. A recent study was conducted using a controlled group of tungsten carbide with cobalt samples with consistent TRS values. It demonstrated a different relationship between the TRS and hardness of Tungsten Carbide with Cobalt compounds.

TRS is a measure of the strength of tungsten carbide. Tensile strength is not used on tungsten carbide because it is too brittle and accurate readings cannot be obtained. As a rule of thumb the tensile strength of tungsten carbide is approx. half of the transverse rupture strength. Transverse rupture strength values are determined by the amount of force needed to break standard test pieces under the same test conditions.

Compressive Strength:

Compressive strength is measured by compressing a right cylinder test piece between two tungsten carbide blocks held in line by an outer sleeve assembly. The compressive strength of tungsten carbide is higher than for virtually all metals and alloys. This high compressive strength makes it possible to compress carbon at 1million P.S.I from man-made diamonds.

Impact Strength:

This measures the resistance of tungsten carbide to shock loading by a drop weight impact test. This is a more reliable indication of toughness than TRS readings.

Weison Advanced Materials Co Ltd founded in 1990s and located at one of the Chinese biggest clustering base of tungsten resources 鈥?Hunan, is a high-tech enterprise that focuses its diligence on research, development, manufacture, sales and technical service base on tungsten material.

Why Tungsten Carbide Grit Is Good for Hardfacing Applications?

Tungsten Carbide Grit is well-known for use in hardfacing applications such as on rotary rock bits and tool joint connections that are used primarily in well drilling where tools must withstand severe abrasion and the stresses of high impacts.

How Tungsten Carbide Grits Are Made?

Manufacturers in the prior art, grits have been made by crushing and screening tungsten carbide compositions. This method produced sharp faceted, irregularly shaped particles with inferior wear resistance. It was recognized in U.S. that the irregularly shaped grit obtained by crushing tungsten carbide compositions were subject to wear problems because of the points and pressures on the rits and the lack of uniformity in the grit particles. This patent teaches a method for preparing tungsten carbide powders whereby spheres, cylinders, ovoids or cubes of tungsten carbide can be obtained for use of a tumbling procedure is mentioned for the production of tungsten carbide grit but no mention is made as to how this procedure is to be carried out.

It has been discovered on the later half that if tungsten carbide powder is combined with a suitable organic binder and agglomerated into particles which are sintered to remove the binder and form tungsten carbide grit, grit with blunt and round particles. These blunt tungsten carbide grits are obtained in good yield with a minimum of unusable fine material. The blunt tungsten carbide grit has superior wear resistance properties as compared to the tungsten carbide grit obtained by crusing tungsten carbide blocks or compacts.

Tungsten Carbide Grit and Hardfacing

The process involved in applying tungsten carbide grit to the surface of hardfacing parts. With hardfacing, the base metal is made tougher and harder through the application of a material (in this case tungsten carbide grit) to its surface. Tungsten carbide grit in fact offers a greater level of protection to surfaces than many or most other traditional hardfacing materials.

Because of the push of the metal cobalt by overseas prices and domestic downstream especially new energy vehicles ternary battery demand, cobalt price jumped all the way, so as to drive the cobalt powder price also synchronous strong gains, cobalt powder prices have beenraising from early 2017s 300 yuan/kgup to 650 yuan/kg, yearly increasing percentage more than 110%, it's dumbfounded.

The prices of raw material go up, led to the production costs have risen sharply for those who producing tungsten products, but at the downstream, tungsten finished products have not up too much at price through the year, the production enterprises generally face income drops, even an embarrassing situation of without profit. Tungsten product manufacturers have been unable to bear the cost of rising raw materials, and allbe forced to raise their prices start from the tail of 2017.

At the beginning of 2018, the raw material is constantly go up at price, tungsten powder now is about RMB282/kg. tungsten carbide powder, recycled tungsten powder is raising for no exception. all the downstream of tungsten industry be forced to adjust their the beginning of 2018. Chinese traditional new year is upcoming. lots of heavy orders need to be finished before Chinese spring festival, the consuming of tungsten powder becoming strong, however, tungsten powder is regulated by green environment restriction orientation, more and more small and medium W powder producers are coerced into shut down, to some extent cause to shortage so that stimulate the raising of tungsten price.

The Prolific Use of Tungsten in the Medical Industry

That obvious, isn it!

The remarkable journey of Tungsten from incandescent lamps to different devices and machines hasn received the hype like other metals do. The mismatch has been evident since steel, copper, gold, and other metals became the memorable topics of discussion.

Tungsten became the top choice of usage in the medical industry due to several reasons. Tungsten properties, such as high melting point, high malleability, and corrosion resistance edge over the advantages of other metals. These exceptional properties leverage the choice of Tungsten collimators than any other material made collimators.

In Computed Tomography (CT) machines, the key manufacturing component is Tungsten. While this metal is used for making detector arrays of scanners, the circular radiation components are made using Tungsten collimators. Certainly, the advantages of using Tungsten are aplenty, but we cite only a few:

  • Tungsten collimators help in reducing the extra radiations, which is why it one of the safest devices for use on a job site.
  • Since the scattered radiation is reduced due to Tungsten collimators, the quality of radiography shots automatically improves.
  • Lauded as an effective radiation shielding material, Tungsten is easy to handle and operate with.
  • Given its non-sparking nature, it also becomes an ideal choice for industrial usage.

Why Is Tungsten An Effective Shielding Material?

Descriptions offered on certain platforms suggest/mention Tungsten as an ffective shielding material without much explanation. Those dealing with metallurgical explorations have a rudimentary knowledge about the material, but not a lot of them have ample time for explaining the ffectiveness of Tungsten in simpler terms. Nevertheless, we are here to offer a lucid account about the same.

The chemical element Tungsten with an atomic number of 74 is a lesser discussed material. It has an atomic mass of 183 grams per mole and has a high melting point (as close as 3400 Degrees Celsius). Before CFLs and LEDs made an entry into our daily lives, the regular households had the incandescent light bulbs for illumination. These bulbs had the Tungsten filament in it.

Given its high tensile strength and highly malleable properties, it became a top choice for real-world applications, whether it is in the aerospace industry or in the medical industry. It can withstand high temperatures, making it a major preference for X-Ray production requirements. Tungsten efficacy in terms of resisting high temperatures without pitting or bubbling justifies its role as an effective shielding material. Moreover, it an effective heat dissipating metal; one of the best alternatives available in the marketplaces.

The Rank Of Tungsten Products In Consumer's Market.

The supply of primary Tungsten products is mainly in China. Though production in Asia has grown significantly, the accounting percentage is low. In terms of consumption, China still dominates the market, followed by the European Union, USA, and Japan. The areas outside these countries account less than 10% of total consumption.

The major application for Tungsten is in the production of Tungsten Carbide or Cemented Carbides. Since these are wear-resistant materials and have intensive applications in the heavy industry, the popularity remains high. Products like c
