Graphite usually occurs in flakes in metamorphosed rocks rich in carbon but it can also be found in veins and in pegmatit Where large deposits are found it is Graphite derives its name from the Greek word graphein to write The material is generally greyish black opaque and has a lustrous black sheen It is unique in that it has properties of both a metal and a non metal It is flexible but not elastic has a high thermal and electrical

Graphite is not an element or compound Its an allotrope of carbon ie it is the same as carbon but has a different crystalline structure Other allotropes of carbon include Diamond Fullerene etc Therefore its represented just using C Symbol of carbon Since Graphite is not an element or aGraphite also has a lower density grams per cubic centimeter than diamond The planar structure of graphite allows electrons to move easily within the plan This permits graphite to
