Silica is a synthetic amorphous silica ultrafine particle (particle ≤ 0.3 μ m), which has the properties of acid resistance, alkali resistance, high temperature resistance and good electrical insulation and dispersion. It is widely used as the thickener and anti sink agent of rubber, sealant, paper, plastic, cable, filler, cover agent and paint ink. SiO2 with high specific surface area has honeycomb porous structure, which can be used as a new catalyst carrier, selective adsorbent and thermal insulation material for aviation in high-tech field. The purity of calcium in wollastonite is over 94%, and the impurities are less. It can be dissolved in wollastonite. It is an ideal raw material for the preparation of silica
