For a long time, foreign suppliers of high-purity quartz powder have been monopolizing the international market. Taking the United States of America as an example, its products mainly include four specifications of IOTA-CG, IOTA-4, IO-TA-6 and IOTA-8. The IOTA series is an internationally renowned high-purity quartz glass raw material. In addition, there are two specifications of high-purity quartz powder produced by Norwegian TQC company: NC-4A and NC-4X, which are mainly used to produce quartz glass crucibles for single crystal silicon drawing.
Although there are many ore sources that can be used to produce high-purity quartz powder in China, due to backward processing methods and lack of basic research in geosciences such as mineralogy and geology of quartz glass raw materials, it is difficult for products to reach the high-purity quartz raw materials. Requirements, this has become one of the important reasons restricting the development of China's high-purity quartz powder industry.
Recently, Yao Xueping, the general manager of JSHH Silicon Industry Co., Ltd. said in an interview with Consumer Daily that the company has reached the advanced level of its international counterparts in ultra-high purity and ultra-fine nano-technology, and produced high-purity ultra-fine nano-scale quartz powder. The purity of silica exceeds 99.999%, which fills two blanks in China, and individual parameters are higher than the products of similar enterprises in the United States, Japan, Germany, Norway and other countries.
Data show: JSHH Silicon Industry Co., Ltd. is committed to producing high-end quartz products. Its products mainly include high-purity quartz sand, crystalline silicon micro-powder, fused silica powder, and high-purity spherical quartz powder. Tons of high-purity quartz powder production line and an annual output of 1500 tons of high-purity ultra-fine silicon micro-powder production line. The high-purity quartz sand production line uses advanced 20,000 Gauss wet magnetic separation, ultrasonic cleaning, high temperature chlorination and other process equipment.
