What is the raw material 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.

The main raw materials for glass production are glass forming agents, glass modifiers and glass intermediates, and the rest are auxiliary raw materials. The main raw materials are oxides, intermediate oxides and out-of-network oxides introduced into glass to form a network; Auxiliary raw materials include clarifier, flux, opacifier, colorant, decolorant, oxidant and reducing agent.

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.

Widely used in buildings, used for wind and shading, belonging to a mixture. In addition, colored glass doped with oxides or salts of certain metals shows color, and tempered glass made by physical or chemical methods. Some transparent plastics (such as polymethyl methacrylate) are sometimes called plexiglass.
