High Purity Vanadium Boride VB2 Powder CAS 12007-37-3, 99%

Description of Vanadium Boride VB2 Powder ：

Vanadium boride, formula VB2, is a compound consisting of vanadium and boron, usually as a black powder or lump. It is a transition metal boride, belongs to the VB group, and is a kind of high-hardness material. 

Vanadium boride oxidizes easily in air, so it must usually be stored in an inert gas or vacuum environment. It has an extremely high melting point and hardness, higher than the hardness of standard ceramic materials like silicon carbide and boron Nitride. The strength and hardness of vanadium boride decrease with the increase in temperature. However, it can still maintain a fairly high hardness at temperatures above its melting point of 200℃. 

It has high melting points and hardness, higher than the hardness of other common ceramic materials like silicon carbide and boron Nitride. Due to its high hardness and melting point, it is an ideal wear-resistant material that can manufacture high-temperature bearings, high-speed cutting tools, etc. In addition, vanadium boride can also be used to create protective coatings to enhance the material's corrosion resistance and oxidation resistance.

Application of Vanadium Boride VB2 Powder ：

Abrasive materials and cutting tools

The vanadium boride's high hardness and melting point make it an ideal grinding material and cutting tool. Due to its excellent wear resistance, vanadium boride is widely used to manufacture grinding tools such as wheels, rods, and cutting blades. These tools can maintain sharpness and durability during grinding and cutting and are suitable for various high-hardness materials, such as glass, ceramics, cemented carbide, etc. 

Wear-resistant parts 

The high hardness and wear resistance of vanadium boride make it an ideal material for manufacturing wear-resistant parts. These wear-resistant parts include bearings, gears, sealing rings, etc., which can maintain good performance in harsh environments such as high temperature, high speed, and high corrosion. Especially in some special occasions, such as aerospace, military equipment, and other fields, the wear resistance of vanadium boride is particularly important. 

Protective coating 

The hardness and melting point of vanadium boride make it stable in high temperatures and corrosive environments to be used as a protective coating. For example, on the outer surface of some high-temperature pipes and equipment, vanadium boride coating can be used for protection to enhance the equipment's corrosion resistance and oxidation resistance. In addition, vanadium boride can be used to manufacture special-purpose coatings, such as optical coatings, electronic device coatings, and so on. 

High-power electronic device 

Vanadium boride is also widely used in the electronics industry, especially in manufacturing high-power electronic devices. Due to its superior thermal conductivity as well as the chemical stability of vanadium, Boride is a good choice for substrate or heat sink. In the operation of high-power electronic devices, vanadium boride can effectively dissipate excess heat and ensure the normal operation of electronic devices. In addition, vanadium boride can also be used to make high-temperature superconducting materials whose superconducting transition temperature is close to absolute zero. 

Composite material 

Vanadium boride can be combined with other materials, such as silicon carbide, boron nitride, etc., to form high-performance composite materials. These composites retain the high hardness and melting point of vanadium boride and increase the advantages of other materials, such as good thermal conductivity and electrical properties. These composite materials have wide application prospects in aerospace, military equipment, and other fields. 

Structural material 

Due to its high melting point and hardness, vanadium boride can be used as a structural material. For example, in high-temperature environments, using vanadium boride as a structural material can effectively resist the erosion of high temperatures and corrosion to ensure the stability and safety of the equipment. In addition, vanadium boride can also be used to manufacture high-temperature bearings, high-speed cutting tools, and other structural components to improve the equipment's working performance and service life. 

Electron beam evaporation material 

Vanadium boride can be used as the source material for electron beam evaporation. In the electron beam evaporation process, vanadium boride can be used as the target material, which can be evaporated into atomic or molecular particles by way of electron beam heating and then deposited on the surface of the substrate to form a coating. This coating has the characteristics of high hardness, high wear resistance, and high melting point and can be used to manufacture various high-performance electronic devices and optical devices.

Production Method of Vanadium Boride VB2 Powder ：

Powder metallurgy process 

Powder metallurgy is a commonly used method to prepare vanadium boride. The method is to mix vanadium pentoxide and boron powder according to a certain proportion and then sintering at high temperatures under vacuum or inert gas protection. In this process, vanadium pentoxide reacts with boron to form vanadium boride crystals. At the same time, some unreacted vanadium pentoxide and boron can be completely reacted through diffusion and recrystallization processes and finally obtain dense vanadium boride materials. 

The specific steps of powder metallurgy are as follows: 

(1) Mixing vanadium pentoxide and boron powder according to a certain proportion to obtain mixed powder; 

(2) The mixed powder is loaded into the graphite mold and sintered at high temperature under the protection of vacuum or inert gas, and the temperature is generally controlled between 1000 and 1100℃; 

(3) In the process of high-temperature sintering, vanadium pentoxide and boron react to form vanadium boride crystals; 

(4) The unreacted vanadium pentoxide and boron are completely reacted through the heat preservation and cooling process, and finally, a dense vanadium boride material is obtained. 

Carbothermal reduction method 

Carbothermal reduction is a method to prepare vanadium boride by using the reducibility of carbon. The method uses carbon to reduce vanadium pentoxide to vanadium metal at high temperatures and then react with boron to produce vanadium boride. 

The specific steps of carbothermal reduction are as follows: 

(1) Vanadium pentoxide and carbon are mixed in a certain proportion and reduced at high temperatures to produce vanadium metal; 

(2) Mixing metal vanadium with boron powder and reacting at high temperature to produce vanadium boride; 

(3) Vanadium boride products are obtained Through the cooling and crushing process.
