Graphite - Wikipedia

Graphite (/ ˈ ɡ r æ f aɪ t /), archaically referred to as plumbago, is a crystalline allotrope of carbon, a semimetal, a native element mineral, and a form of coal. Graphite is the most stable form of carbon under standard conditions.Therefore, it is used in thermochemistry as the standard state for defining the heat of formation of carbon compounds.
