Glass is an amorphous inorganic non-metallic material. It is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as main raw materials, and a small amount of auxiliary raw materials are added. of. Its main components are silica and other oxides. [1] 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. It is widely used in buildings, used for wind and light transmission, and is a mixture. There are also colored glass mixed with oxides or salts of certain metals to show color, and tempered glass made by physical or chemical methods. Sometimes some transparent plastics (such as polymethyl methacrylate) are also called organic glass.
