What are the main raw materials for making glass?

Quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.

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.

Extended data

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.

Glass is usually divided into oxide glass and non-oxide glass according to its main components. There are few varieties and quantities of non-oxide glasses, mainly chalcogenide glasses and halide glasses. The anions of chalcogenide glasses are mainly sulfur, selenium and tellurium. , can cut off short wavelength light and pass yellow, red, near and far infrared light. It has low resistance and has switching and memory characteristics. Halide glass has low refractive index and small dispersion, and is often used as optical glass.
