Physical and chemical properties and production methods of vanadium carbide

Vanadium carbide is a transition metal carbide, the molecular formula is VC.

What are the physical and chemical properties of vanadium carbide?

Vanadium carbide black cubic crystals. The melting point is 2810°C, the boiling point is 3900°C, and the relative density is 5.77. Slightly harder than quartz. It can be made by reducing vanadium pentoxide with coke. Mainly used in the manufacture of vanadium steel. It can be used as an additive for carbide cemented carbide.

How to produce vanadium carbide?

Vanadium carbide (VC or V2C) has excellent chemical properties such as high hardness, oxidation resistance, corrosion resistance, small specific gravity, and good stability. At home and abroad, in order to improve the strength and hardness of cemented carbide and titanium-based cermets, vanadium carbide is often added as a particle strengthening phase to cemented carbide and titanium-based cermets. The purity requirements are very high (currently there is no unified standard for vanadium carbide for cemented carbide or cermet. Generally speaking, vanadium carbide accounts for more than 99.0wt%, and vanadium carbide+free carbon≦99.9wt%). Even in the equilibrium state, there are still certain vacancies in the vanadium carbide character. These vacancies are relatively easy to be filled by nitrogen, oxygen atoms, and occasionally boron and silicon atoms, making it extremely difficult to prepare high-purity vanadium carbide. At present, the main raw material of VC produced at home and abroad is vanadium pentoxide or vanadium trioxide as the raw material, and the corresponding carbon source is added.

Overview of vanadium carbide VC powder

Vanadium carbide VC powder is an inorganic compound with a molecular formula of VC. Black cubic crystal, melting point 2810°C, boiling point 3900°C, relative density 5.77, Moher hardness 9-9.5, slightly higher than quartz, it may be the hardest metal carbide known. Vanadium carbides are 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. Because 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 will be converted to V2C at higher temperatures.

Vanadium carbide, chemical formula VC, molecular weight 62.95, carbon content 19.08%, density 5.41g/cm3, melting point 2800℃, boiling point 3900℃. Vanadium carbide is a gray metal powder with a NaCl type cubic structure and a crystallization constant of 4.182. Cemented carbide has stable chemical properties and excellent high temperature performance. It can be used in cutting tools and steel industry, and can also be used as an additive to refine WC cemented carbide to improve alloy properties.

Application of vanadium carbide VC powder

The application range of vanadium carbide VC powder is very wide. Among them, adding vanadium carbide to steel can improve the comprehensive wear resistance, corrosion resistance, toughness, strength, ductility, hardness and thermal fatigue resistance of steel, and can be used as a wear-resistant material. -Different cutting and abrasion resistant materials. Resistant to tools.

Vanadium carbide VC powder is widely used as a new type of catalyst due to its high activity, good selectivity, good stability, resistance to hydrocarbon reaction "catalyst poisoning" and other advantages.

Vanadium carbide VC powder can also be used as a new carbon source for synthetic diamond. Vanadium carbide is used as a grain inhibitor in the field of cemented carbide and cermets, which can effectively prevent the growth of WC grains during the sintering process.

Vanadium carbide VC powder is used as an additive to cemented carbide to refine carbide crystals, thereby increasing the hardness of the blade.
