Abstract

<PICT:0675933/III/1> Titanium or zirconium dioxide is reduced by mixing the finely divided dioxide with particles of magnesium, heating the mixture in an inert atmosphere (e.g. argon) to initiate the reaction and form magnesium vapour, and retaining the vapour within the reaction mixture for at least one hour at at least 1100 DEG C. The dioxide is stated to be reduced beyond the sub-oxide state. The charge 8 is placed in a container 2 and is separated from a dry lime insulation layer 9 by a plate 10, the container being placed within a water-cooled furnace 1 having an inlet 5 for the inert atmosphere and a tube 6 for thermocouples 7.
