<p>Pure known and novel refractory oxides in a novel cationically homogeneous crystalline form with particle size diameters in the nanometer (<100nm) range, which ordinarily are transparent and which can have one or both of electrostatic and magnetic properties due to the nanometer size diameters of its particles, can be produced by the successive steps of heating a hydrated halide or a hydrated halide-oxide mixture containing the metal cation or cations of the refractory oxide, homogeneously dispersed in a colloidal-like state, to a temperature at which a solid state hydroxyhalide complex containing only the cation or cations of the refractory oxide is produced; which complex when it is fully formed is then heated to a higher temperature until converted to a solid state oxyhalide complex; which complex when it is fully formed is then heated to a higher temperature until converted to a solid state metastable activated oxyhalide complex; which complex when it is fully formed is then heated to a higher temperature at which it is converted to the novel cationically homogeneous refractory oxide end product.</p> |
