Home > AboutAbout Quartz

We offers high purity quartz sand with Sio2 between 99.99% and 99.9993%. Uniquely high quality quartz material in Donghai area combined the advanced purifying technology and facilities ensure our quality consistent and stable. Our products can be generally divided into 3 grades QSL、QSS、QSE according to different applications. The characteristics of low phosphor and boron make it ideal for polycrystalline silicon, quartz crucible, semiconductor and solar industries. A range of testing items is inspected for each batch. They include microstructure, particle size, impurity content, residual hydroxyl ion(OH) content, color impurities, etc. We will provide high quality sand to the customers all over the world in the field of lighting, solar energy and semiconductor.
