Also called silica sand or quartz sand, silica is made of 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.

How To Make Pure Sand or Silica - thoughtco

Mix the two solutions together. The resulting gel that forms at the bottom of the liquid is orthosilicic acid. Place the orthosilicic acid into a heat-safe glass or porcelain dish and heat it over a burner flame for about 5 minutes. The orthosilicic acid dries to form silicon dioxide, SiO2, which is your pure sand.
