Preparation of finely particulate silicon dioxide
Abstract
Abstract FINELY PARTICULATE SILICON OXIDES ARE PRODUCED FROM COARSE PARTICULATE SILICON DIOXIDE USING A LIQUID STABLISHED PLASMA BURNER. HYDROCARBONS ARE USED AS THE STABILISING LIQUID, AND THE COARSE PARTICULATE SILICON DIOXIDE IS REDUCED BY THE HYDROCARBON PLASMA JET LEAVING THE PLASMA BURNER, AND A PART OF THE HYDROCARBON WHICH WITH IS EVAPORATED AND DECOMPOSED IN THE ARC ZONE IS WITHDRAWN TOGETHER WITH THE LIQUID HYDROCARBON STABILISING MEDIUM, WHICH IS RE CYCLED, SEPARATED FROM THE LIQUID, AND USED AS CARRIER GAS FOR FEEDING THE COARSE PARTICULATE SILICON DIOXIDE. FINELY PARTICULATE SILICON MONOXIDE IS INITIALLY FORMED, AND MAY BE RECOVERED AS SUCH, OR OXIDIZED AT THE ANODE OF THE PLASMA BURNER TO SILICON DIOXIDE.
