Quartz is also the main component of silica, transparent quartz crystal, that is, we often say crystalSilica can be made into glass, but it is impossible to process it into crystals. It is a natural jade, the main component of which is silica
Sand silicaBecause of the different crystal structures of crystalline silica, divided into quartz, tridymite and cristobalite. Three pure quartz colorless crystal and transparent prismatic quartz crystal. If the name contains trace impurities in the crystal with different colors, amethyst, Citrine, topaz. Ordinary sand is quartz crystal fine. There are sand (iron impurity) and white sand (less impurities, Jiao Chunjing).
Silica widely exists in nature, and other minerals constitute the natural silica rock. There is also called silica, is a kind of solid hard refractory silica. Also called silica, chemical formula SiO. Nature exists in two crystalline silica and amorphous silicon oxide two.
