Abstract

A high temperature reactor is fitted with a plasma gun at an anode chamber and is provided with a graphite cathode. The reactor is cooled by means of pipes in the refractory lining of the reactor, and rests on essentially horizontal bearings. The charge to be melted e.g. oxides or oxide mixtures is fed from above at an angle .alpha. at most 90.degree. to the main axis of the reactor in the direction of the plasma stream, and the molten product is tapped off at an exit port which is also close to the entry port of the plasma stream so that the plasma stream covers and therefore heats the area around the exit port.
