Introduction to glass

Glass is an amorphous inorganic non-metallic material. It is generally made from 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 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 an irregular structure.
It is widely used in buildings to isolate wind and light, and is a mixture. There are also colored glasses that are mixed with oxides or salts of certain metals to give them colors, and tempered glass made by physical or chemical methods. Sometimes some transparent plastics (such as polymethylmethacrylate) are also called plexiglass.
