Tungsten boride, also known as black powder, has the following physical properties: a molecular form WB2, metal conductivity with a soluble solution in aqua regia. Purity>99%
Particle size range: 10-20um

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 boron-containing boride (WB4) has a three dimensional grid of boron molecules. We combine the thermodynamics stability with the principle calculation and study the thermodynamic and mechanical properties.
The highest boron to identify tungsten must be WB3 composed by two-dimensional plane grids of boron, not WB4. It was discovered that the shear modus in the tungsten borate system transformed its energy of 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 dioxide. 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 material directly.
It can also cause hypoborate to form during the sintering phase, and bulk compact material with WB2 is not possible.

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 obtain tungsten boreide. Continue the reaction to form W2B. Cool and crush this product.
2. Tungsten powder and stoichiometric boran powder are mixed at a ratio of 2:1 in a vacuum atmosphere or an argon environment at temperatures between 1200degC and 1300degC, to form two tungsten boreides.
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.

Tungsten Boride ?
Wear-resistant layer for wear parts.
WB compounds exhibit high melting points, high hardness, good conductivity, wear resistance as well as high temperature resistance and corrosion. 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 (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.
1) Prepare the workpiece with the tungsten rich coating. This includes a workpiece base, a tungsten layer and a gradient layer of tungsten.
2) To produce a hard material from tungsten biboride, this method uses a mechanochemical process to synthesize the tungsten triboride powder in argon, using 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 pressures. The prepared tungsten Diboride Bulk Material has several 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, it's important that you store your tungsten Boride WB2 in a dry and cool room. You should not expose this powder to air. WB2 powder must also not be exposed to stress.
