Vanadium Carbide VC Powder CAS 12070-10-9

Vanadium carbide is an inorganic compound. The vanadium carbide formula is VC. Black cubic crystals. The vanadium carbide melting point is 2810°C, the Vanadium carbide boiling point is 3900°C, and the relative density is 5.77. The hardness is 9-9.5 Moher, slightly higher than quartz. It may be the hardest metal carbide known. Vanadium carbide is commonly found in vanadium metals and alloys. Vanadium carbide can be prepared by reducing vanadium pentoxide with coke. Mainly used in the manufacture of vanadium steel. It can be used as a cemented carbide additive for cemented carbide.

It has the same structure as vanadium monoxide and crystallizes in the rock salt. Since VC and VO are mutually soluble, VC samples usually contain oxide impurities. It is made by heating vanadium oxide and carbon at about 1000°C. Although VC is thermodynamically stable, it converts to V2C at higher temperatures.

Performance of of of Vanadium Carbide VC Powder :

Vanadium carbide, Chemical formula VC, Molecular weight 62.95, Carbon content 19.08%, Density 5.41g/cm3, Melting point 2800ºC, Boiling point 3900ºC.Vanadium carbide is a gray metallic powder with a cubic system structure of NaCl type, crystalline constant is 4.182A. The carbide is chemically stable and has excellent high-temperature properties. It can be used in the cutting tool, and the steel industry can also be used as an additive to fine the WC cemented carbide crystal to improve the properties of the alloy.

How is Vanadium Carbide VC Powder produced? 

1. Complete the carbon powder and the vanadium dioxide under high vacuum conditions. The carbonized vanadium is prepared at 1300 ° C or higher. 

2. Pure VC can be made by the gas-phase reaction method. The hydrogen-containing tetrachloride VCl4 vapor and hydrocarbon gas (methane, benzene, etc.) are connected to a tungsten wire directly energized to heat it. To avoid metal vanadium and wires of tungsten produced at the beginning of the reaction, the temperature of the tungsten wire is maintained at 1400 ° C or lower. After a very strong VC layer is formed, it is raised to 2000 ° C to complete the carbonization reaction. The precipitation of the tungsten wire is a gray-white crystalline. 

3. Preparation by metal vanadium. Put the metal vanadium powder or the hydrogenated vanadium powder (particle size should be less than 325 mesh, preferably below the mixture of micrometers) and carbon black (mixed by the mine, and the carbon black content is more than 5% ~ 10 %). Pressure molding. When the metal is mixed with high pressure (about 3 tons/cm 2), the vanadium is pressed (about 1 ton/cm 2) when pressurized. This pressurized powder is stored in the graphite crucible (in about 1-33322Pa vacuum) heated to 1800 ~ 2000 ° C, maintained for one h so that the carburization (reaction temperature and holding time are determined by the particle size of the feedstock, reaction performance), Fill the amount, etc.). 

4. Adopt a reduction method. The carbon powder is thoroughly mixed with vanadium dioxide, and the carbonized vanadium can be prepared at a temperature of 1300 ° C or higher under high vacuum conditions.

Applications of Vanadium Carbide VC Powder:

Superhard material
Vanadium carbide has high hardness and wear resistance, so it is a superhard material.
