Product Description



High reflectivity silver plated surface quartz glass tube is made of SiO2 and coated by silver in special industrial technology. It is a kind of base material with excellent physical and chemical performance. The softening point of Quartz glass is around 1730°C. It can be used for a long time under 1100°C, and for a short period of time at the highest temperature of 1450°C. Except hydrofluoric acid, quartz glass has no chemical reaction with other acid materials. The acid capacity is 30 times that of ceramic and 150 times that of stainless steel. Especially at high temperatures, the chemical stability is unmatched by any other engineering materials. In addition, Quartz glass has good transmission from the UV to IR spectrum, over 90% transmitted at vision, and especially in the UV spectrum, it can reach more than 80%. The resistance value of quartz glass is equivalent to ten-thousand times of common glass. It is an excellent electric insulation material with good performance, even under high temperatures.


The silver mirror has a high reflectivity in the visible and near-infrared spectral range, and the silver layer coated with a protective film has a good cleanability and firmness. It is 18% at 300nm. At 500nm, the reflectivity is 90%
