Diamond
Diamond
Diamond is an allotrope of Carbon. It has a crystalline
lattice. In diamond each carbon atom undergoes sp3
hybridization and lined to four other carbon atoms by using hybridized orbitals
in tetrahedral fashion. The C-C bond length is 154 pm. The structure extends in
space and produces a rigid three-dimensional network of carbon atoms. In this
structure directional covalent bonds are present throughout the lattice.
It is very difficult to break extended covalent bonding and
therefore, diamond is a hardest substance on the earth.
Uses
- It is used as an abrasive for sharpening hard tools.
- It is used to manufacture of tungsten filaments for electric light bulbs.
- It is used in making dies.
