These materials combine the strength, hardness and wear resistance of carbon with the corrosion resistance and self lubricating properties of graphite. They can be impregnated with various materials to enhance its properties and used in applications where traditional lubrication is unsuitable.
The C-C bond length is 0.142 nm within the layer and C-C distance between 2 layers is 0.34 nm. Graphite is used for making metallurgical crucible. Properties of Graphite Graphite is an allotrope of carbon which is used for making moderator rods in nuclear power plants. Its properties are as follows: A greyish black, opaque substance.
Graphite is considered an archaic industrial mineral since it has been mined for its useful properties (lubrication, pigmentation, writing, etc.) for thousands of years. The word graphite is derived from the Greek word graphein, which means, to write. A version of the word graphein is still retained by carbon scientists as the word graphene ...
