Graphite is one of the natural minerals which is chemically composed of only carbon atoms Carbon is available in pure form as coal graphite and diamond Graphite is also very stable and resistant to damage by environmental exposure Like diamond it has high melting pointIf the pressure is increased to 10 atmospheres carbon graphite is observed to melt at 176 C Boiling point o C K Carbon has the highest melting/sublimation point of all the elements and in the form of diamond has the highest thermal conductivity of any element

Why does Graphene have a higher melting point than Diamond up vote 3 down in stare and it s based on thermodynamics But at room pressure neither diamond nor graphene are stable allotropes graphite is They are metastable has higher melting point than diamond because of the partial double bond character of C C bonds So the bond The Gmelin rare earths handbook lists 176 C and 176 C as two melting points given in the literature the most recent reference Handbook on the chemistry
