Fused Silica Powder First Grade, aslso Called Silicon Dioxide, with High Purity and Whiteness Sio2 99.9% as Refractory Raw Materials (325 Mesh, 200 Mesh,120Mesh)
Also Know as A grade with high purity with Sio2 around 99.7%-99.99%.
We choose high purity quartzite from Donghai and Xinyi areas as raw material. After acid washing treatment, the crystalline silica is transformed into amorphous silica with a small amount of impurities in a resistance furnace at a high temperature of 1700ºC. After special mechanical processing, screening, iron removal and other picking treatments, the high purity quartzite is formed into lumps, granules and powdered products.
