Crystalline silica has a higher melting point (1610 °C) than iron, copper or aluminium and other common metals. This enables castings to be made by pouring molten metal into moulds made from silica sand and a binder. The physical and chemical characteristics of the sand are important. In the past naturally clay bonded moulding sands were used.

Luckily, silicon is one of the most widely available elements in the form of sand. Before silicon can be cut into thin wafers, however, it has to be purified, as otherwise the photoeffect will not be very efficient. Purity levels for solar cells do not have to be as high as in chip applications. Solar-grade purity is 99.999% (5N) as opposed to electronic-grade silicon purity of up to 99
