High Purity Tungsten Boride WB2 Powder CAS 12007-09-9, 99% |

About Tungsten Boride WB2:
Tungsten-boride consists of tungsten combined with 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.
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. 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 different phases’ structure 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 principal calculation and then study the mechanical and thermodynamic properties of the tungsten carbide system.
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 three-dimensional boron molecules. 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, high-pressure sintering process is used to achieve the dense tungsten boron diboride. 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 powder is not known, so it’s difficult to make WB2 from tungsten or boron powder.
It can also cause hypoborate to form during the sintering phase, and compact bulk materials with WB2 being the main phase will not be 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. Then, continue the reaction to form W2B. Finally, cool the mixture 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 metal powder stoichiometric tungsten is mixed with the 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 conductivity and wear resistance. They are also resistant to corrosion, high temperature and wear. 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.
1) Prepare the workpiece with the tungsten rich coating. This includes a substrate and successively arrange a tungsten gradient layer and a top tungsten film. In the direction of thickness, the boron in the tungsten gradient layer increases.
To produce a hard tungsten-diboride material, the method uses a mechanochemical process to synthesize the tungsten-diboride powder in argon. This method is able to obtain compact tungsten-diboride bulk 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 wide variety of purposes, including cutting tools, corrosion-resistant material, and new shielding material.

Storage condition of Tungsten-boride WB2 (Powder)
As the damp reunion can affect WB2 dispersion, and its use, tungsten Boride WB2 should be stored in a dry and cool room. WB2 powder must also not be exposed to stress.
