China made major technological breakthrough in the preparation of ultra-pure quartz sand.
Recently, Xi'an Northwest Nonferrous Geological Research Institute Co Ltd has made a major technological breakthrough in the preparation of high-end high-purity quartz materials. After years of continuous technological research, the research team focused on quartz sandstone with 99.85% SiO2 content and successfully developed a full-process, independently controllable purification process system for high-purity quartz. Tested by the China National Center of Quality Inspection & Testing on Deep Processing Silicon Products, the purity of the produced high-purity quartz sand reaches 99.9994%, and the total amount of key impurity elements is precisely controlled within 6ppm. This achievement marks a key step forward for the company in the independent preparation technology of high-purity quartz materials.
