Graphite is a mineral that has a high melting temperature (3,500 °C), conducts electricity well, is soft and flakes easily.
Graphite is the most stable form of carbon present in nature under standard conditions and represents its allotropic form made up of numerous sheets of graphene stacked on themselves.
Graphite is used to make pencils, refractory material, lubricants, dyes, brushes for rotating electrical machines and electrodes for electrical discharge machining.
Every mined material is a little different from the next.
Graphite from a mine in Sri Lanka will be different from the graphite dug out of a mine in America.
Because minerals lack continuity, it makes the creation of a scalable production practice quite difficult but not impossible as Graphite will be every time composed of a numbers of single foil of graphene!
