'''Graphite''' is a form of high-purity [[carbon]] which occurs on Earth as a [[mineral]]. It can also be artificially produced from [[silicon carbide]].<br />
[[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.<ref name=Cairncross>B. Cairncross - ''Field guide to rocks and minerals of Southern Africa'' 2004. ISBN 978-1-86872-985-2 p. 123</ref>

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

==Uses==
* [[Refractory]]

==Open issues==
* How common are graphitic rocks on Mars?
* How common are graphite-containing meteorites on Mars?
