SILICA QUARTZ

Quartz is a hard, crystalline mineral composed of silicon and oxygen atoms and the second most abundant mineral in the planet’s crust, after the feldspar family of minerals. Quartz is a defining constituent of granite and other felsic igneous rocks. It is common in sedimentary rocks such as sandstone and shale as well as schist, gneiss, quartzite and other metamorphic rocks. Quartz crystals, which are hexagonal in shape, vary enormously in size and colour.

This versatile mineral is both durable and chemically inert and demonstrates excellent heat resistance as well as electrical properties. Following transformation into silicon (Si) through gaseous reduction at high temperature, it becomes a valuable metalloid for the production of solar panels, semiconductors and electronics, aluminum and steel alloys and for the construction industry.
