Graphite | Geology for Investors
Graphite is used to line the inside of moulds into which molten metal is poured. Graphite is ideal for this purpose because it can withstand temperatures up to 3000°C, provided oxygen is absent. Also, its natural lubrication properties prevent the metal from sticking to the moulds. In the presence of oxygen, graphite will burn at 700°C, with ...
