What is titanium carbide

2018-09-11
Relative molecular mass: 59.91
Density 4.93g/cm3
Melting point 3160 ° C, boiling point 4820 ° C
TiC light gray, cubic crystal system, insoluble in water, with high chemical stability, almost no chemical reaction with hydrochloric acid, sulfuric acid, but soluble in aqua regia, nitric acid, and hydrofluoric acid, also soluble in alkaline In the solution of the oxide.
It can be prepared by heating bone cement and titanium dioxide in an electric furnace. It is an important component of cemented carbide. Used as a cermet, it has high hardness, corrosion resistance and good thermal stability. It can also be used to make cutting tools. Used as a deoxidizer in the steel industry.
Titanium carbide is a typical transition metal carbide. Its bond type is composed of ionic bonds, covalent bonds and metal bonds in the same crystal structure, so titanium carbide has many unique properties. The structure of the crystal determines the basic characteristics of titanium carbide with high hardness, high melting point, wear resistance and electrical conductivity. Titanium carbide ceramics are the most widely developed materials for transition metal carbides of titanium, zirconium and chromium.
