3-300mm transparent polished fused silica tube

3-300mm transparent polished fused silica tube is a kind of high purity special industrial technology glass, mainly used for applications in high temperature environment. This quartz tube is made of high purity silica (SiO2) with high light transmittance and hot topic stability. Their chemical composition contains almost no harmful impurities, which makes them have good chemical stability at high temperature and almost no chemical reaction with other acids. The softening point temperature of these quartz tubes is about 1730 ℃, which can be used for a long time at around 1100 ℃, and the maximum use temperature for a short time can reach 1450 ℃.

Transparent polished fused silica tubes are widely used in many fields, such as electric fire buckets, electric baking stoves, electric heaters, etc., as heating materials. They are also used in halogen lamps, mercury lamps, metal halide lamps, halogen heating tubes, carbon fiber heating tubes and other quartz lamps, etc., as high temperature resistant materials. In addition, these quartz tubes can be further processed according to customer requirements, such as neat cutting, burning, bending, sealing and frosting, etc.

In terms of physical properties, transparent polished fused silica tubes have a very small coefficient of thermal expansion, which allows them to withstand drastic temperature changes. Their main size range is 3-260mm outer diameter and 1200-1500mm length. The preparation of these quartz tubes requires the selection of the inner diameter and wall thickness of the quartz tubes according to the diameter of the diffused silica gel sheet.

3-300mm transparent polished fused silica tube is a high-quality, high-performance material suitable for a variety of high-temperature applications.
