Quartz glass has excellent physical and chemical properties: 1. High temperature resistant: long time working at 1,100°C,for short time working at the highest temperature at 1450°C , softening point is 1,730 °C. 2. Corrosion-resistant: except the hydrofluoric acid, it almost has no reaction with acid material, Acid-resistant is 30 times to that of ceramics and 150 times that of stainless steel,under the high temperature the chemical properties is stable. 3.Good thermal stability: thermal expansion coefficient is minimal, can stand the sharp changes in temperature. From 1,100°C into water of normal room temperature it will not burst. 4.Good transparency for light: Good transparency from the ultraviolet ray to infrared spectral bands, Visible light transmittances is 93%, ultraviolet spectrum area biggest through rate can reach more than 80%. 5. Good electrical insulation: High resistance compared with ordinary glass.. Applied in the area of light source, semiconductor, telecommunication industry, metallurgy, building materials, chemical, machinery, electric power, environmental protection,. Quartz tube can be divided into: transparent quartz tube, filter ultraviolet quartz tube, color quartz tube, etc
