About Tungsten Boride WB2:
Tungsten-boride consists of tungsten and boran. They are characterized by their high hardness. Vickers hardness is 20GPa of WB or diboride tungsten WB2 and 30GPa of WB4 for loads greater than 3N.
Tungsten boride density is 10.77 and tungsten boride melting point is about 2900degC. It is not a degrader of water, but can degrade aqua regina.
It is made by heating boron-tungsten powders to high temperatures.
Tungsten-boride possesses comprehensive properties including high melting points, high hardness, and chemical stability. This new superhard material has a very high melting point. This material is important for the military as it's bulletproof.
The rich phase diagrams of tungsten-alloys and the structure of the different phases have been changing for more than fifty years.
The highest boride (WB4) has a three-dimensional grid of boron molecules. We combine the thermodynamics stability with the principle calculation and study the mechanical and thermodynamic properties of possible structures of tungsten carbide systems.
The highest boron to identify tungsten must be WB3, composed of plane boron molecules in two dimensions, and not WB4, which is composed of grids of boron atoms in three dimensions. It was discovered that the shear modus of tungsten's borate system transformed its energy. It was found that mechanical properties were closely related to thermodynamic stability.
A high temperature and pressure sintering process is used to achieve the dense tungsten biboride. This is due to WB2's free diffusion coefficient. This reduces the amount of tungsten diboride and increases its cost.
The boron content in tungsten and the boron powder is not easily measurable, so it's difficult to produce WB2 bulk materials from these powders.
It can also cause hypoborate to form during the sintering phase, and bulk material that is WB2 in its main phase will not be compacted.

How is Tungsten Boride WB2 produced?
1. After mixing and grinding the raw materials tungsten and boran, heat them and react above 1400°C to get tungsten boreide. Continue the reaction to form W2B and finally cool and crush it to obtain the finished product.
2. Tungsten is combined with stoichiometric powder boron at a molar ration of W:B=2 to 1, and sintered under vacuum or in an argon atmosphere between 1200degC and 1300degC, to obtain two tungsten bore.
3. Use the solid-phase method. Tungsten boride can be prepared by combining metal tungsten with boron. The reaction formula can be found below. The stoichiometric metal powder tungsten is mixed with elemental boron, then ground, molded and heated at temperatures above 1400degC. Continue the reaction, resulting in W2B. The product is obtained by cooling and crushing the W2B.

Applications Tungsten Boride
Wear-resistant layer for wear parts.
WB compounds exhibit high melting points, high hardness, good conductivity, high temperature resistance, corrosion resistance and wear resistance. The compounds are also used for structural materials, wear resistant materials, and electrodes. Materials and many other fields. Tungsten boride can be produced through the reaction between metal tungsten (metal tungsten) and element boron heated in an electric oven. It has all the properties of the W-B series compounds, and it has a wide range of applications in the future.
The unique coating structure allows for high bonding between layers, as well as a gradual change in the coefficients of thermal expansion and elastic modulus between layers.
2) To produce a bulk of tungsten Diboride using a high-temperature sintering, the method uses a mechanochemical process to first synthesize the tungsten Diboride powder in argon with high-purity W and B powders as raw materials. This method is able to obtain a compact tungsten-diboride material by sintering at normal temperatures and pressures. The tungsten-diboride bulk material is characterized by excellent properties including good stability, hardness, and neutron absorption. It can be used for a variety applications, including cutting tools, new shielding materials, and corrosion-resistant material.

Tungsten Boride Powder:
As the damp reunion can affect the WB2 dispersion performance, and its use effects, tungsten Boride WB2 should be stored in a dry and cool room. WB2 powder must also not be exposed to stress.
