Water glass, ceramics, ordinary cement, quartz glass, what are these chemicals?

Water glass chemical formula is Na2SiO3.9H2O, usually quartz and caustic soda (NaOH) wet production, or with quartz and soda ash (Na2CO3) dry production, both need high temperature.

The main component of these substances, ceramics, cement, and quartz, is SiO2. In addition, SiO2 is also used to make optical fibers.Elemental silicon is used to make solar panels, chips and other materials
