About Vanadium Carbide VC Powder:
Vanadium carbide is an inorganic compound whose molecular formula is VC. Black cubic crystals. The melting point is 2810°C, the 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. Can be used as cemented carbide additives for cemented carbide.
It has the same structure as vanadium monoxide and crystallizes in the rock salt structure. Since VC and VO are mutually soluble, VC samples usually contain oxide impurities. It is made by heating vanadium oxide and carbon at a temperature of about 1000°C. Although VC is thermodynamically stable, it converts to V2C at higher temperatures.

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 a temperature of 1300 ° C or higher.
2.Pure VC can be made by gas-phase reaction method. The hydrogen-containing tetrachloride VCl4 vapor and hydrocarbon gas (methane, benzene, etc.) is connected to a tungsten wire directly energized to heat it. In order to prevent metal vanadium and tungsten wire generated in the initial stage 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, 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 1 h, so that the carburization (reaction temperature and holding time is determined to 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:
Vanadium Carbide has a wide range of applications. Among them, the addition of vanadium carbide to steel can improve the comprehensive properties of steel wear resistance, corrosion resistance, toughness, strength, ductility, hardness and thermal fatigue resistance, and can be used as a wear-resistant material in different cutting and wear-resistant tools.
Vanadium Carbide is widely used as a novel catalyst due to its high activity, selectivity, stability and resistance to "catalyst poisoning" in hydrocarbon reactions.
Vanadium Carbide can also be used as a new carbon source to synthesize diamond. The most important role of vanadium carbide is as a grain inhibitor in the field of cemented carbide and cermet, which can effectively prevent the growth of WC grains during sintering.
Vanadium carbide is used as an additive to cemented carbide, to refine the carbide crystals and thereby get an increased hardness of the inserts.
Vanadium Carbide can be used as a grain refiner in cemented carbide, cutting tools, and steelmaking industries, which can significantly improve alloy properties.
Vanadium Carbide is used for cutting hard alloys, producing wear-resistant films and semiconductor films.
