Graphite - Wikipedia
Graphite (/ ˈ ɡ r æ f aɪ t /), archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure.It occurs naturally in this form and is the most stable form of carbon under standard conditions.Under high pressures and temperatures it converts to diamond.Graphite is used in pencils and lubricants.

types of graphite - Saint Jean Carbon
There are three principal types of natural graphite, each occurring in different types of ore deposit The mineral graphite is an allotrope of carbon. Unlike diamond (another carbon allotrope), graphite is an electrical conductor, making it a semimetal. Graphite is the most stable form of carbon under standard conditions. As a result it is used in thermochemistry as the standard state for ...

What Are the Uses of Graphite? | Sciencing
Graphite occurs naturally as flakes and veins within rock fractures or as amorphous lumps. The basic crystalline structure of graphite is a flat sheet of strongly bonded carbon atoms in hexagonal cells. Called graphenes, these sheets stack above each other to create volume, but the vertical bonds between the sheets are very weak.
