Application Of Quartz

Crystalline quartz has a higher melting point than iron, copper and aluminium. This enables castings to be produced by pouring molten metal into moulds made out of silica sand and a binder. Castings form the basis of the engineering and manufacturing industries. Quartz and cristobalite flours are the main components in investment casting (also called precision casting) for the production of specialist products such as jewellery, dental bridges, aviation turbines and golf clubs.
