Ultrafine silica powder is made from high-grade silica raw materials through special grinding and precision grading process, with fine particle size and controllable distribution. Ultrafine silica powder is widely used in industries such as electronic materials, paint and coating, silicone rubber, special ceramics, etc. The particle size of ultrafine silicon powder is usually D50=1-8 microns, and the particle size distribution is controllable. 99.22% Water 0.17% Loss on ignition 0.25% Fe2O3 0.023% Moh's hardness 7
