Description

Quartz, also called deep quartz or α quartz, is a mineral with the chemical composition SiO2 and trigonal symmetry. It is the stable form (modification) of silicon dioxide on the earth's surface and, after feldspars, the second most common mineral in the earth's crust. At a temperature of over 573 °C (under a pressure of 1 bar) deep quartz changes into high quartz by changing the crystal structure. With a Mohs hardness of 7 quartz belongs to the hard minerals and serves as a reference on the scale of up to 10 (diamond) according to Friedrich Mohs. It often forms well-developed crystals of a great variety of shapes and colours, whose crystal surfaces exhibit vitreous luster. Quartz has no cleavability, breaks shell-like like glass and shows a greasy shine on the fractured surfaces. Quartz is one of the most important minerals in industry and is of worldwide importance both as a building material and as a raw material for the ceramics, glass and cement industries. Quartz gravel and broken quartz are raw materials for the production of silicon. In addition, quartz and its coloured varieties have been valued as gemstones since time immemorial.
