High temperature quartz tube, also known as quartz glass tube, is made of silica [1] special industrial technology glass, is a very good base material. Quartz glass has a series of excellent physical and chemical properties such as:

 1, high temperature

    Quartz glass softening point temperature of about 1730 ℃, can be used at 1100 ℃ for a long time, the shortest time the maximum temperature of up to 1450 ℃,

 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 tube thermal expansion coefficient is minimal, can withstand severe temperature changes, the quartz glass heated to 1100 ℃ 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, especially in the UV spectrum, the maximum transmittance of up to 80 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. The following are the same as the "

    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.

Types of quartz tubes

    Quartz tube can be divided into the following: transparent quartz tube (diameter 1.5mm - 300mm), filter UV quartz tube, color quartz tube.
