quartz glass
Quartz glass, a special material mainly composed of silica, has been widely used in many fields due to its unique advantages. Firstly, quartz glass has extremely high transparency, especially in the ultraviolet and infrared regions, which makes it of great value in optical applications. Secondly, quartz glass has excellent high-temperature resistance, with a softening point of up to 1650 ° C, which can maintain stability in high-temperature environments. In addition, quartz glass has an extremely low coefficient of thermal expansion, which minimizes its size change under temperature changes, ensuring its use in precision instruments. Meanwhile, quartz glass has good chemical stability and almost does not react with acidic or alkaline substances other than hydrofluoric acid, making it suitable for various corrosive environments. These advantages make quartz glass have broad application prospects in fields such as optics, electronics, and chemical engineering.
Quartz glass
Quartz glass is made by melting materials containing silica, such as crystal, silica, and silicon tetrachloride, at high temperatures. Its silicon dioxide content is much higher than ordinary glass, with quartz glass having a silicon dioxide content of 99.999%. Has excellent optical performance, not only has excellent visible light transmittance, but also transmits ultraviolet and infrared rays. Meanwhile, quartz glass is a good acid resistant material. In addition to hydrofluoric acid and thermal phosphoric acid above 300, 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 30 times that of acid resistant ceramics and 150 times that of nickel chromium alloys and ceramics. It is resistant to high temperatures, heat shock, and has a particularly small coefficient of thermal expansion
