| Abstract: | With the rapid development of strategic emerging industries, high purity quartz has become one of the key basic raw materials for many cutting-edge fields. The strategic position of high-purity quartz is becoming more and more prominent, and the dependence of China's high-end high-purity quartz sand on foreign countries is still high, so it is urgent to accelerate the key technology of high-purity quartz sand preparation in China. Based on the overview of high purity quartz resources at home and abroad, the impurity characteristics in high purity quartz were analyzed from two aspects: the existence of impurities and the influence of impurities on product quality, and the progress of two key technologies for deep purification of high purity quartz, acid treatment method and heat treatment method, were systematically summarized. |
