| titleOfInvention | A method for producing high-activity and high-purity fumed silica |
| abstract | The invention discloses a formula and method for producing high-activity and high-purity fumed silicon dioxide. The reaction combustion mass ratio is: silicon tetrachloride: oxygen: hydrogen = 200.00:75.34:2.38; the preparation formula of silicon tetrachloride is according to the quality The ratio is: silica: coke: pure chlorine: TH‑904＝100.00:48.00:227.00:1.00; the silica content in precipitated silica is greater than 96.00%, potassium fluorosilicate is 1.00‑2.00%, and sulfate is less than Equal to 0.80%; the present invention can rationally utilize the by-product precipitated silica of producing highly active potassium fluoride to improve resource utilization; Potassium fluorosilicate of the present invention and TH-904 are converted into silicon tetrachloride in silicon dioxide The reaction process has a strong catalytic synergistic dispersion effect, which reduces the reaction conditions, thereby reducing the production cost and the complexity of the reaction system, and at the same time improving product quality. |
