'''Graphite''' is a [[Crystallinity|crystalline]] [[Allotropes o carbon|allotrope o carbon]], a [[semimetal]] an a [[native element mineral]]. Graphite is the maist stable form o carbon unner [[staundart conditions]]. Tharefore, it is uised in [[thermochemistry]] as the [[staundart state]] for definin the [[standard enthalpy o formation|heat o formation]] o carbon compoonds.
