What is carbide?
Solution
Carbide is a carbon compounded with a non-metal (such as boron, calcium, or silicon) or metal (such as in cobalt, tantalum, titanium , tungsten, or vanadium). Metal carbides are characterized by their extreme hardness and resistance to high temperature , and are used as abrasives, and in cutting, drilling, grinding, and polishing tools.
These are also divided into subgroup like
- Salt-like (saline) carbides
- Covalent carbides
- Interstitial carbides
- Intermediate transition metal carbides
- Molecular carbides
Structure of Carbide
Three covalent bonds hold two carbon atoms together in the carbide structure. There are two pi-bonds among these three covalent bonds. The lateral overlap of the p-orbitals results in the formation of these pi-bonds. Sigma bonds are another type of bond that are created when the s-orbitals overlap one another directly. The carbon in the carbide structure exhibits sp hybridization. One lone pair is present on each carbon atom.
