Characteristics and application of high-purity quartz sand ...

2021-8-30  Quartz sand includes ordinary quartz sand, refined quartz sand, high-purity quartz sand, and fused quartz sand. High-purity quartz sand generally refers to fine quartz powder with a SiO 2 content of more than 99.9%. It is a neutral inorganic filler and does not react with the filler. It is a very stable mineral filler.
