What is High Purity Quartz

What is High Purity Quartz? High-purity quartz is a rare high-tech strategic mineral resource in the world. It is an irreplaceable mineral raw material for the manufacture of high-tech quartz glass and a rare generic high-value-added mineral resource required by strategic emerging industries. Based on the opinions of researchers and the current international technical level, we can call quartz with a purity of ω(SiO2)≥3 N~5 N and ω(Fe2O3)<10×10-6 as high-purity quartz. 6 N to 7 N is called ultra-high-purity quartz.High-purity...
