General description

Graphite is an allotrope of carbon. Graphite is a nonmetallic showing high electrical conductivity. Synthetic graphite can be prepared by heating carbonaceous precursor in an inert atmosphere.
Graphite is the most stable allotrope of carbon under standard conditions.The only nonmetallic conductor of electricity. Graphite powder is used as an additive to alter the magnetorheology and electrical conductivity of magnetorheological elastomers (MREs).

Application

Graphite powder has been used:
  • in the synthesis of single sheet graphene nanoflakes
  • in the preparation of graphite based magnetorheological elastomers
  • free standing film like cantilever sensor in piezoelectric device
  • to study its use as a catalyst for wet peroxide oxidation.

Oxidation of carbon dust was studied.
Synthesis of graphite based MR elastomers have been reported. It may be used in the preparation of graphite oxide and anode in lithium ion battery.
