    摘要: A method is disclosed for synthesizing a crystalline metal oxide powder material containing two or more uniformly distributed metal elements. Crystalline, water containing, oxygen containing inorganic acid salts of the metals are heated to liquefy the salts. The apparent solution contains a uniform mixture of the metal elements. The water is removed from the liquid and the resulting powder calcined in air to decompose the acid salts to a mixed metal crystalline oxide. The method is particularly useful to make doped LiNiO2 type crystals using hydrated nitrate or nitrite salts of Li, Ni and the dopant elements. Examples of useful salts are LiNO3.H2O, Ni(NO3)2.6H2O, Co(NO3)2.6H2O, Al(NO3)3.9H2O, and Mg(NO3)2.6H2O.

    摘要: A method for producing fine or ultra fine powder particles comprising mixing a metal alkoxide with a non-metallic hydride in an organic solvent, agitating the mixed solution, and then burning the mixed solution. The burning process comprises igniting the solution directly or burning the solution in situ. A self-sustaining flame will result. When the precursor solution burns, the metallic compound will be co-fired with the organic solvent. As a result, fine or ultra fine particles of mixed metal will burst from the flame, or thrust through the flame and be synthesized.
