- the fumed silica is usually obtained by flame hydrolysis. In this method, a vaporized or gaseous hydrolyzable silicon halide is reacted with a flame formed by combustion of hydrogen and an oxygen-containing gas. The combustion flame thereby provides water for the hydrolysis of the silicon halide and sufficient heat for the hydrolysis reaction. A silica produced in this way is called fumed silica.
