Natural Graphite | Asbury Carbons

Since graphite is virtually pure carbon, its formation at high temperature requires that the “local” oxygen concentration (in the earth’s crust) be low. Graphite typically forms only under reducing conditions since at high temperature it combines with oxygen to form transient species such as carbon monoxide (CO) and carbon dioxide (CO 2 ).
