High purity quartz sand is a quartz sand product with extremely high purity, which is widely used in many high-end fields, such as semiconductors, photovoltaics, electronics, optics, etc.

High purity quartz sand, also known as high purity quartz, refers to SiO2 purity greater than 99.9% of the quartz sand series of products. It is a quartz crystal raw material with high SiO2 purity and certain particle size composition obtained from natural quartz ore after purification. The concept should have three characteristics of purity, particle size and mineral phase at the same time. Our high purity SiO2, suitable for the most stringent purity requirements of the application scenarios.

Product features:
1. High purity: SiO2 purity is greater than 99.9%, impurity content is very low.
2. Excellent chemical stability: can resist the erosion of a variety of chemical substances.
3. High insulation and voltage resistance: It is widely used in electronic and electrical fields.
4. Very low coefficient of volume expansion: it can still maintain stable physical properties under high temperature environment.
5. Good optical performance: such as high transmittance, low refractive index, etc., suitable for optical field
