Quartz tube is made of silica special industrial technology glass, is a very good base material. Quartz glass has a series of excellent physical and chemical properties.
1, high temperature. Quartz glass softening point temperature of about 1730 degrees, can be used at 1100 degrees for a long time, the shortest time the maximum temperature can reach 1450 degrees.
2, corrosion resistance. In addition to hydrofluoric acid, the quartz glass is almost no chemical reaction with other acids, the acid resistance is 30 times the ceramic, 150 times the stainless steel, especially at high temperature chemical stability, is any other engineering materials are not Match.
3, good thermal stability. Quartz glass thermal expansion coefficient is minimal, can withstand severe temperature changes, the quartz glass heated to 1100 degrees or so, into the room temperature water will not burst.
4, good light transmission performance. Quartz glass in the ultraviolet to infrared spectrum of the entire spectrum have better light transmission performance, visible light transmittance of 93% or more.
5, good electrical insulation performance. Quartz glass resistance value equivalent to 10,000 times the ordinary glass, is an excellent electrical insulation material, even at high temperatures also have good electrical properties.
Quartz glass has been widely used in various fields such as electric light source, semiconductor, optical communication, military industry, metallurgy, building materials, chemistry, machinery, electric power, environmental protection and so on because of its excellent physical and chemical properties.
