[0002] 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 the main raw materials, and a small amount of auxiliary raw materials. Its main components are silicon dioxide and other oxides. The chemical composition of glass is Na2SiO3, CaSiO3, SiO2. The main component is silicate complex salt. It is an amorphous solid with irregular structure. Glass is widely used in medical devices, daily furniture and household appliances.
