Overview of TiC
TiC is light gray, cubic crystal system, insoluble in water, and has high chemical stability. It hardly reacts with hydrochloric acid and sulfuric acid, but it can be dissolved in aqua regia, nitric acid, and hydrofluoric acid, and it is also soluble in alkaline Oxide solution.
It can be made by heating bone charcoal and titanium dioxide in an electric furnace. It is an important component of cemented carbide. Used as a cermet, it has the characteristics of high hardness, corrosion resistance and good thermal stability. It can also be used to make cutting tools. Used as a deoxidizer in the steelmaking industry.
The characteristic of TiC
Titanium carbide is a typical transition metal carbide. Its bond type is composed of ionic bonds, covalent bonds and metal bonds mixed in the same crystal structure, so titanium carbide has many unique properties. The structure of the crystal determines that titanium carbide has the basic characteristics of high hardness, high melting point, wear resistance and electrical conductivity. Titanium carbide ceramics is the most widely developed material among the transition metal carbides of titanium, zirconium and chromium.
TiC is an iron-gray crystal with metallic luster. It belongs to the NaCl type simple cubic structure. The lattice constant is 0.4329 nm. The carbon atoms and titanium atoms are equivalent at the lattice position, and the TiC atoms are bonded by strong covalent bonds. It has several characteristics 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 extremely 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. It has a wide range of applications in other fields.
