Tungsten carbide button bit is formed by insetting the tungsten carbide button into the bit. Compared with the flake bit, the distribution of button bit is more flexible. The number and position of the side and middle tooth can be determined according to the diameter of gouge and the load of cutting. 

After tungsten carbide button is turned, grinded or polished, the residual oil, dirt, oxide and so on are tightly combined with the surface of tungsten carbide which will cause serious dirt. It requires that the product should be clean, dry and free from corrosion.

The coarse grain tungsten carbide has a series of advantages, such as good crystallizability, less structural defects and large subcrystal size. It is used in the production of hard alloys. The mining tools, stamping dies, drilling and mining tools can also be applied to hard surface materials such as spray and spray welding.

The advantage of tungsten resources in China is gradually disappearing, the resource crisis is prominent. At present, with tungsten resources becoming more and more complex and difficult to choose, all kinds of high impurity and low grade tungsten ore raw materials will become the main body of raw material treatment for tungsten smelting enterprises in the future. In addition, as China encourages the development of recycling economy, the recovery and utilization of various tungsten smelting residues will also receive more and more attention from enterprises.

Tantalum-tungsten (Ta-W) alloy is widely used due to its high density, high melting point, high ductility, modulus of elasticity, good processing properties, high temperature strength, high corrosion resistance, weldability and low brittle-to-ductile transition temperature (BDTT). It is used in aerospace, defense, military, chemical, and nuclear industries. With the development of 3D printing technology, Ta-W powder has also become one of the main 3D printing materials, mainly used for printing complex or miniature Ta-W alloys, which also puts higher requirements on the performance of the powder.

Nickel-tungsten catalysts are widely used in hydrotreating and hydrocracking. The main components are about 25% tungsten trioxide, 2% nickel oxide, 50% alumina, 5% silica, and a small amount of iron, vanadium and other substances. Waste nickel-tungsten catalysts contain metals such as tungsten and nickel. If they are recycled, they will generate huge economic benefits and avoid environmental pollution caused by the waste of nickel-tungsten catalysts.

In recent years, the improvement of the metallurgy and the improvement of the concentration capacity of the oxidized tungsten-molybdenum ore have been greatly improved. For example, Gansu, Qinghai, Xinjiang, Inner Mongolia and other provinces now, has the ability to have a froth float on tungsten-molybdenum ore with a tungsten trioxide content of 3 to 8%, and a molybdenum content of 2.5 to 12.5%; The Guangdong and Guangxi regions have the ability to have a froth floatation on tungsten-molybdenum ore containing 20 to 45% of tungsten trioxide and 10 to 25% of molybdenum.

Tungsten carbide (WC) is the main raw material for the production of cemented alloy. The main production method is one-step method and two-step method. At present, the main method for producing WC powder is two-step method: Firstly reducing the tungsten oxide to tungsten powder with hydrogen. Then, tungsten powder is carbonized to form WC powder at a high temperature. In the production practice, the method is not suitable for producing ultrafine WC powder.

Tungsten Carbide Button has a series of excellent properties, such as high hardness, abrasion resistance, good strength and toughness, heat resistance, corrosion resistance and so on. Meanwhile, the properties of high hardness and abrasion resistance keep the tungsten carbide button in shape basically at 500℃ and maintain the high hardness at 1000℃.

It is well known that in addition to titanium dioxide, tungsten trioxide is one of the most studied photocatalyst materials in recent years. Due to the introduction of nanotechnology, the photocatalytic performance of tungsten trioxide has been greatly improved. A photocatalyst is a substance that stimulates a reaction by absorbing light without changing before or after the reaction. The photocatalyst has the ability to absorb energy in sunlight, prevent infection and disease outbreak by destroying bacteria and provides disinfection, and purifie water and air.
