Transparent fused quartz glass rod

Quartz rod for the company's products one of advantage, specializing in the production of high purity transparent quartz rod, the existing specification 1-50 mm, length of 1.24 m. I company production of high quality quartz rod surface finish well, bubble gas line strict control, bending degree not more than chief 3 ‰. The purity of quartz rod mainly depends on raw materials, with four chlorinated silicon and other raw materials to produce high purity quartz rod can reach six a nine (99.9999%), mainly for the optical fiber production; In the purification of high quality natural quartz purity can achieve four nine, used in semiconductor industry; With high quality natural quartz production of common purity quartz rod in three of the nine or so, to high strength electric light source of production. Quartz rod thermal expansion coefficient of tiny, is only 1/10 of the glass-1/20, has the very high resistance to urgent hot urgent cold sex, clear quartz rod in electric furnace in 1100 °C hot 15 minutes, and then put into cold water, repeated test also won't break, quartz rod of softening point is about 1730 °C temperature, use continuously temperature of 1100-1200 °C, the short time the highest temperature of 1450 °C use. Because of quartz rod has high purity, high temperature resistance and low coefficient of thermal characteristic, is widely used in the ocl halogen lamp pressure bridge stick, fiber optic lighting, quartz fiber manufacturing, semiconductor wafer processing, etc.
