Preparation of Silicon Dioxide SiO2 with high dispersibility in organic solvents;

(1) Preparation of Silicon Dioxide SiO2 with high dispersibility in organic solvents;

(2) The acidifying agent reacts with the silicate aqueous solution, and the sediment is separated and dried to prepare Silicon Dioxide SiO2;

Silicon Dioxide SiO2

(3) Alkali metal silicate is mixed with inorganic acid to form Silicon Dioxide SiO2 hydrosol, which is then converted into gel particles, which are dried, washed with hot water, dried again, and calcined to obtain Silicon Dioxide SiO2; (chemical precipitation method)

(4) Silicon Dioxide SiO2 prepared by carbonation of water glass; (carbonation precipitation method)

(5) Preparation of edge-smooth aspheric Silicon Dioxide SiO2 by spray granulation.
