Crystalline silica powder

Crystalline silica powder is processed from natural crystalline quartz with SiO₂ content 99.6%‑99.8% and low impurity level. Mohs hardness 7.0. It features stable dielectric property, low linear expansion coefficient, good thermal conductivity and high refraction coefficient. Multiple particle‑size grades are available with controllable particle‑size distribution, good powder flowability and excellent filling performance with cost‑effective advantage. Widely applied in EMC packaging, painting, semiconductor, optics, aviation electronics and fine chemical industry.
