Good light transmission performance of quartz glass in the ultraviolet to the infrared spectral band has good light transmittance, visible light transmittance is more than 93%, especially in the ultraviolet spectral region, the maximum transmittance is higher than 80.
Quartz glass tube is made of silica dioxide [1] special industrial technology glass, is a very good basic material. Quartz glass has a series of excellent physical and chemical properties, such as: 1, high temperature resistant quartz glass softening point temperature of about 1730 DEG C, can be used in 1100 DEG C for a long time, short time maximum temperature is 1450 degrees centigrade, 2, corrosion except hydrofluoric acid, quartz glass hardly with other chemical acids the reaction, its acid resistance is 30 times 150 times of ceramic, stainless steel, especially the chemical stability at high temperatures, any other engineering materials are incomparable. 3, good thermal stability of quartz glass thermal expansion coefficient is extremely small, can withstand the temperature changes, the quartz glass is heated to 1100 degrees Celsius, the water will not burst into the room.
Electrical insulation performance is good, quartz glass resistance value is equivalent to ten thousand times of ordinary glass, is an excellent electrical insulation material, even in high temperature also has good electrical performance. Because of its excellent physical and chemical properties, quartz glass has been widely used in many fields, such as electric light source, semiconductor, optical communication, military industry, metallurgy, building material, chemical, mechanical, electric power, environmental protection and so on. Quartz tube types can be divided into the following categories: transparent quartz tube (outer diameter 1.5mm--300mm), filter quartz tube, color quartz tube and so on.
