About Tungsten Boride WB2:
Tungsten-boride consists of tungsten boron. 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.
The powders of boron, tungsten and other metals are heated at a high temperature.
Tungsten-boride possesses comprehensive properties including high melting points, high hardness, and chemical stability. It is a superhard, high melting-point material. 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. The first step is to combine the thermodynamics stability with the principle calculation. We then study the thermodynamics stability and mechanical properties.
The highest boron to identify tungsten must be WB3, composed of two-dimensional plane grids of boron, not WB4, composed of three dimensional grids. The borate system for tungsten's shear modulus was found to change the energy of its formation. 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-diboride due to WB2's free diffusion coefficient. This reduces the amount of tungsten diboride and increases its cost.
The boron content is not easily measurable when preparing WB2 from tungsten or boron powder.
It can also cause hypoborate to form during the sintering phase, and it is impossible to obtain compact bulk material that has WB2 as its main phase.

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. Then, continue the reaction to form W2B and cool down and crush it to get 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.

Application of Tungsten Boride - WB2
Wear-resistant layer for wear parts.
WB compounds exhibit high melting points, high conductivity and wear resistance. They are also resistant to corrosion, high temperature, and high-temperature. 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 possesses the excellent properties of WB series compounds, and has broad applications in the future.
The coating structure is unique and can increase the bonding strength of the layers. It also increases the thermal expansion coefficient and elastic modulus of the layers.
2) To produce a hard material from tungsten biboride, this method first uses the mechanochemical method of synthesizing tungsten triboride powder in argon with high-purity W and B powders as raw materials. This method is able to obtain compact tungsten-diboride bulk material by sintering at normal temperatures and pressure. The prepared tungsten Diboride Bulk Material has several excellent properties including good stability, hardness and neutron absorption. It can be used for a wide variety of purposes, including cutting tools, corrosion-resistant material, and new shielding materials.

Tungsten Boride Powder Storage Conditions of
It is recommended that the WB2 tungsten powder be stored in a dry and cool room. WB2 powder must also not be exposed to stress.
