Process for manufacturing oxides

Abstract

The present invention relates to a pyrogenic process for manufacturing metal oxides or metalloid oxides wherein a metal precursor and/or a metalloid precursor is introduced into a flame formed by burning a gas mixture comprising oxygen and hydrogen, wherein at least a part of the hydrogen and at least a part of the oxygen have been obtained from electrolysis of water or an aqueous solution, using electrical energy, at least a part of which has been obtained from a renewable energy source, and wherein water (H2O) is introduced into the flame, and wherein the total molar ratio TRON of oxygen gas to nitrogen gas TRON=n(O2):n(N2) of all streams introduced into the flame prior to ignition combined is TRON≥0.25 and ≤1.
