| Quartz rod has high purity, strong heat resistance, and low coefficient of thermal expansion characteristics.Single-ended halogen lamps for bridging rod, fiber optic lighting, quartz fiber manufacturing, semiconductor wafer processing.Quartz rod as one of our superior products, the existing standard 1-50mm, length 1.24m.Our co***ny produces high-quality quartz rod polished surface, bubble gas line is controlled strictly, length of curvature of not more than 3 бы.Depending on the purity of the quartz rod material, with high-purity silicon tetrachloride and other raw materials purity quartz rod can reach (99.9999%), mainly for fiber production; with the purification of high quality natural quartz purity can reach 99.99%, for the semiconductor industry; natural quartz with high-quality production of ordinary purity quartz rod about 99.9%, for the production of high-strength electric light.Coefficient of thermal expansion of quartz rod small, only glass' 1/10-1/20, with high resistance to acute thermal quench, tran***rent quartz rod in the furnace of burning at 1100 ℃ for 15 minutes, and then into cold water, repeatedly test will not break, the softening point temperature of the quartz rod is about 1730 ℃, continuous use temperature of 1100-1200 ℃, short-term maximum temperature up to 1450 ℃.As the quartz rod has high purity, strong heat resistance, low coefficient of thermal expansion characteristics, are widely used in single-ended halogen bridging rod, fiber optic lighting, quartz fiber manufacturing, semiconductor wafer processing. |
