Exceptional Purity for Critical Applications
High Purity Quartz Filler is for applications that demand very high purity. In these cases, regular industrial fillers cannot meet the requirements. Our product uses the best quartz ore from the Huangshan area. We process it through deep acid washing, fine grinding, precision grading, and high-intensity magnetic separation. The final SiO₂ content stays above 99.7%. Iron content is below 0.03%. Total impurities are extremely low. This level meets the strict purity needs of semiconductor packaging, optical fiber manufacturing, optical glass, and high-end coatings.
A Dedicated Quality System for High Purity
Making High Purity Quartz Filler requires high technical skill and strong quality control. We have set up a full quality assurance system for this product. We use dedicated raw materials, special production lines, and independent testing. Our 2 labs have a full set of precision instruments. We use conductivity meters, laser particle size analyzers, and dielectric loss testers. These allow us to test purity, particle size, and electrical properties accurately. Our senior engineer team monitors the whole production process. They optimize process parameters at every step. This ensures every batch of product meets the highest standards.

High-End Applications and Custom Service
High Purity Quartz Filler serves the most demanding applications across many industries. In semiconductor packaging, it is a key filler for high-performance epoxy molding compounds. Its ultra-low ion content and low alpha particle emission are critical for chip reliability. In fiber optics, it is a basic raw material for preforms. Its high purity and uniformity directly affect transmission loss. In optical glass and precision lenses, it provides excellent light transmission and very low color. We can customize the purity, particle size, and electrical properties for your needs. The minimum order is 1 ton.
