Quartz oxygen cylinder

quartz glassIt is made of substances containing silicon dioxide, such as crystals and silica. Made by high-temperature melting of silicon dioxide as raw material. Its silicon dioxide content is much higher than that of ordinary glass, and the silicon dioxide content of quartz glass is generally99.999%Quartz glass has excellent optical properties, not only with particularly good visible light transmittance, but also with ultraviolet and infrared transmittance.

quartz glassIt is a good acid resistant material, except for hydrofluoric acid and300In addition to hot phosphoric acid above a certain temperature, it can withstand corrosion from sulfuric acid, nitric acid, hydrochloric acid, aqua regia, neutral salts, carbon, and sulfur at high temperatures. Its chemical stability is equivalent to that of acid resistant ceramics30Double, equivalent to nickel chromium alloy and ceramics150It is resistant to high temperatures, thermal shock, and has a particularly small coefficient of thermal expansion.
