Abstract

A device for obtaining metal oxides by combustión of a metal halide with an oxidizing gas and a combustible gas, characterized by A) a lower reaction chamber constituted by an impermeable outer wall and by a thin and permeable metallic inner wall, arranged concentrically, there being a gas distribution zone between both; B) a base supporting the reaction chamber, provided with a cooled lower part and an upper part provided with a feed line for the fuel gas and with communication openings with a gas distribution zone as well as with a gas supply line. Feed for the mixture of reactive gases; C) a superior reaction chamber communicated with the lower reaction chamber and also constituted by an impermeable outer wall and a thin, permeable inner metallic wall, arranged concentrically, with a gas distribution zone comprised between both; D) a central part of separation between both reaction chambers, with a cooled lower part and an upper part provided with a supply conduit for the gas and communication openings with the upper gas distribution area, as well as for E) an upper guide piece, provided with a cooled lower part and an upper part provided with inlet and outlet openings for the gas.
