Graphite

Graphite is a good electrical conductor and has a high fusion point and good lubricating properties. It is used as an anode in batteries, as a refractory material in industries producing molten metal for crucibles and blast furnace linings, and to replace asbestos in brake shoes for heavier vehicles. Graphite is also used in pencils.
