TiC is a gray metallic powder with sodium chloride type cubic crystal system and high melting point, high hardness, good thermal stability, high chemical inert ability to iron and steel, wide range of applications, and it’s an essential material in making cemented carbide and cermet. Heeger Materials provides high-quality TiC granulated powder with narrow particle size distribution and high purity at a competitive price.

The titanium carbide powder has a Mohs hardness of 910, a microhardness of 3000kg/mmz and an elastic modulus of 2940N/mm2, a bending strength of 240-400N/nn, and it is insoluble in water and hydrochloric acid. It is soluble in alkaline nitric acid and aqua regia.

It can be produced by the following ways:

1. Carbon thermal reduction method.

This method uses microwave energy to heat the raw materials, and the dielectric loss of the material converts the electric power into heat energy to make the carbon thermally reduce, forming TiC crystals. This method is simple and economical, but its yield and quality are limited.

2. Reaction method.

This method uses sponge titanium and carbon black as the raw materials, mixing them in proportion and pressing them into a Ph10mm x 5mm cylinder to prepare the precursor. After the reaction, the precursor is loaded into a metal restraint outer cylinder and subjected to an explosion shock wave in order to achieve self-reaction of the titanium oxide and carbon. The detonation ash is collected to obtain the TiC. The powder is then screened to remove impurities, calcined in the furnace and ground to get the final product.
