Process for preparing mixed oxides with average diameters lower than 10 nanometer

摘要

Production of mixed oxides comprises reacting alcoholates of titanium, zirconium, niobium, tantalum or their mixtures with metal hydroxides, metal carboxylates, metal hydroxycarbonates, metal carbonates or their mixtures of lithium, sodium, potassium, magnesium, calcium, strontium, barium, zinc, cadmium, aluminum, gallium, yttrium, lanthanum, praseodymium, neodymium, samarium, dysprosium, europium, lead, bismuth, or their mixtures in a 1-8 C alkanol, in a glycol ether or their mixtures at 50-200[deg] C.
