Also called silica sand or quartz sand, silica is silicon dioxide (SiO 2). Silicon compounds are the most significant component of the Earth's crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.
Depending on how the silica sand was formed, quartz grains may be sharp and angular or rounded. For industrial use, pure deposits of silica capable of yielding products of at least 98% SiO2 are required. Silica sand may be produced from sandstone, quartzite and loosely cemented or unconsolidated sand deposits.
