Graphite

Graphite is a form of high-purity carbon which occurs on Earth as a mineral. It can also be artificially produced from silicon carbide.
Coke and charcoal are not as pure as graphite because, while the carbonizing process does boil off volatiles in their production, non-volatile ash remains.

Physical characteristics

Graphite has a hardness of 1 to 2 on Mohs' scale, a black streak, a lustre varying from metallic to dull and earthy, a hexagonal crystal system and specific gravity between 2.1 and 2.23.^[1]

Occurence

Graphite occurs on Earth in igneous and metamorphic rock, sometimes as metamorphosed coal. It can also be found in limestone. Some meteorites contain graphite.
