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.
TiC is an iron-gray crystal with metallic luster. It belongs to the simple cubic structure of NaCl type, with a lattice constant of 0.4329 nm and a space group of Fm3m. Carbon atoms are equivalent to titanium atoms at the lattice position, and TiC atoms are strong. The covalent bond combines several properties similar to metals, such as high melting point, boiling point and hardness. Hardness is second only to diamond, has good thermal and electrical conductivity, and even exhibits superconductivity at very low temperatures. Therefore, TiC is widely used in the manufacture of cermets, heat-resistant alloys, hard alloys, anti-wear materials, high-temperature radiation materials and other high-temperature vacuum devices. The composite materials prepared by them are used in machining, metallurgy, minerals, aerospace and fusion reactors. And other fields have a wide range of applications.
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.
