    Silica. Also called silica sand or quartz sand silica is silicon dioxide SiO 2. Silicon compounds are the most significant component of the Earths 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.
