Carbides

A carbide is a compound composed of carbon and a less electronegative element. Carbides can be classified according to chemical bonding in the compounds as follows:salt-like ionic carbides, covalent compounds, interstitial compounds, intermediate transition metal carbides.

The carbides of transition metals of groups four, five, and six are often described as interstitial compounds. They are chemically quite inert, have metallic properties, and are refractory. Titanium carbide, Silicon Carbide and tungsten carbide are important industrially and are used to coat metals in cutting tools.Carbides are combinations of special metals and carbon to form very hard materials greater than that of hardened steel. They are therefore used in applications requiring extreme strength such as machine tool bits, drilling and mining operations.

The special combination of physical and structural properties of carbides gives them special industrial uses. These include:Resistance to abrasion which is very high and they easily outlast hard steel grades.Resistance to deflection: Compared to steel bars of the same grades, carbides have an elasticity modulus of up to three times more which equals to one third deflection compared to the steel bars.

Different types of carbides include: Boron Nitride, Silicon Carbide, Tungsten Carbide, Tantalum Carbide, Chromium Carbide, Hafnium Carbide, zirconium Carbide, Vanadium Carbide etc.
