Carbide
In
chemistry
, a
carbide
is a compound composed of
carbon
and a less
electronegative
element. Carbides can be generally classified by chemical bonding type as follows: (i) salt-like, (ii)
covalent compounds
, (iii)
interstitial compounds
, and (iv) "intermediate"
transition metal
carbides. Examples include
calcium carbide
(CaC
2
),
silicon carbide
(SiC),
tungsten carbide
(WC) (often called simply
carbide
when referring to machine tooling), and
cementite
(Fe
3
C), each used in key industrial applications. The naming of ionic carbides is not systematic.
