The chemical composition of quartz is silicon dioxide (SiO2), and high-purity quartz sand means that the SiO2 content is higher than 99.9%. Quartz sand is a silicate raw material obtained through crushing and purification. To make high-purity and ultra-high-purity quartz raw materials, it is necessary to remove all impurities except silica.
