Q
What is the composition of glass?
A

Composition of Glass


(1) Ordinary glass also called float glass . (Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2)


(2) Quartz glass (Glass made of pure quartz as the main raw material, the composition is only SiO2)


(3) Tempered glass (same composition as ordinary glass)


(4) Potassium glass (K2O, CaO, SiO2)


(5) Borate glass (SiO2, B2O3)


(6) Colored glass (adds some metal oxide during ordinary glass manufacturing process. Cu2O - red; CuO - blue green; CdO - light yellow; CO2O3 - blue; Ni2O3 - dark green; MnO2 - Purple; Colloid Au - Red; Colloid Ag - Yellow)


(7) Color-changing glass (high-grade colored glass using a rare earth element oxide as a colorant)


(8) Optical glass (In the ordinary borosilicate glass raw materials, add a small amount of light sensitive substances, such as AgCl, AgBr, etc., and then add a very small amount of sensitizer, such as CuO, so that the glass becomes more light sensitive)


(9) Rainbow glass (made by adding a large amount of fluoride, a small amount of sensitizer and bromide to common glass raw materials)


(10) Protective glass (appropriate auxiliary material is added during the ordinary glass manufacturing process, which has the function of protecting personal safety by preventing the penetration of strong light, strong heat, or radiation. For example, gray - dichromate, iron oxide absorbs ultraviolet light And partially visible light; blue-green—nickel oxide, ferrous oxide absorbs infrared and partially visible light; lead glass—lead oxide absorbs X-rays and r-rays; dark blue—dichromate, ferrous oxide, iron oxide absorption Ultraviolet, infrared, and most visible light; addition of cadmium oxide and boron oxide absorbs neutron flux.


(11) Glass-ceramics (also known as crystallized glass or glass-ceramics, made by adding crystal nuclei such as gold, silver, and copper to ordinary glass, instead of stainless steel and precious stones, for radome and missile heads, etc.).


(12) Glass fibers (fibers with diameters of several micrometers to several thousand micrometers drawn or blown from molten glass, the same composition as glass)


(13) Glass filament (ie long glass fiber)


(14) FRP (Reinforced plastic with strength similar to steel obtained by compounding epoxy resin with glass fiber.)


(15) Cellulose paper (transparent cellulose film made of viscose solution)


(16) An aqueous solution of water glass (Na2SiO3), named after some of the same components as common glass)


(17) Metallic glass (glassy metal, generally produced by rapid cooling of molten metal)


(18) Fluorite (fluorite) (colorless and transparent CaF2, used as a prism and a light mirror in optical instruments)


(19) Plexiglass (polymethyl methacrylate)
