Abstract
Finely divided metal oxides are prepared by introducing into a fluidized bed of particulate material at a temperature of at least 700 DEG C. a first metal halide (not F) and an oxygenating gas and simultaneously introducing at a point higher in the bed a second metal halide. Metals specified are titanium aluminium zirconium. Halide specified:-chloride. Oxygenating gas specified:-air or O2. Particulate size specified:-50-2000 m . The second halide is introduced at a distance above the first so that the first is oxidized before contact with second. The first halide may be a mixture of those specified or may be the same as the second and preferably forms sub-pigmentary particles of oxide. When the first and second halides are the same the amount introduced as the first halide is in the range 5-90% of the whole halide introduced. When they are different the first is in the range 0.5-10% of the total weight of metal oxide produced. The oxygenating gas may be introduced at any point in the bed or mixed with the first metal halide. The second metal halide is added so that it mixes rapidly and uniformly with the products of the first reaction. To the reactants may be added an alkali metal halide (potassium specified), water or silicon halide in the range 0.001-5% of the total weight of metal oxide produced. In an example a bed of particulate TiO2 was heated to 1050 DEG C. and TiCl4, preheated to 200 DEG C. and containing SiCl4 in an amount to give 0.125% silica by weight of the TiO2 produced, was passed in as a first halide. Oxygen preheated to 150 DEG C. and containing AlCl3 to give 0.62% alumina by weight of the TiO2 produced was passed in at the same level. Above these inlets is introduced preheated TiCl4. Good yields of TiO2 in a finely divided state are produced.
