Quartz glass tube is made of silicon dioxide, special industrial technology glass, is a very good foundation material. Quartz glass has a series of excellent physical and chemical properties, such as:

1, high temperature. The softening point of quartz glass temperature of about 1730 ℃, 1100 ℃ in the long-term use, short-term maximum temperature up to 1450 ℃,
2, corrosion resistance. In addition to hydrofluoric acid, the quartz glass with almost no other acid substances chemical reaction, the acid resistance is 30 times that of ceramics, stainless steel 150 times, especially in high temperature chemical stability, is not any other engineering materials Comparable.
3, good thermal stability. Quartz glass thermal expansion coefficient is very small, can withstand severe temperature changes, the quartz glass heated to 1100 ℃ or so, into the water at room temperature will not burst.
4, light transmission performance. Quartz glass in the entire ultraviolet to infrared spectral band has good light transmission, visible light transmittance above 93%, especially in the ultraviolet spectrum, the maximum transmittance of up to 80 or more.
5, electrical insulation performance. The resistance value of quartz glass is ten thousand times of that of ordinary glass. It is an excellent electric insulating material, and has good electrical properties even at high temperature
