What is the chemical composition of glass?

Glass is an amorphous inorganic nonmetallic material, which is generally made of various inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.). ) as the main raw material, and add a small amount of auxiliary raw materials.

Its main components are silicon dioxide and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O CaO 6SiO2, etc. The main component is silicate double salt, which is an amorphous solid with irregular structure.

Performance characteristics:

In addition, glass can be divided into tempered glass, porous glass (foam glass with a pore size of about 40nm, which is used for seawater desalination and virus filtration), conductive glass (used as electrode and aircraft windshield), glass-ceramics and opaque glass (used for lighting devices and decorative items, etc.). ) and insulating glass (used as window glass).
