複合酸化物微粒子の合成方法及び複合酸化物微粒子

Method for synthesizing fine compound oxide particles and fine compound oxide particles

Abstract

PURPOSE: To obtain fine compound oxide particles having a large surface area and a desired particle diameter by mixing fine metal oxide particles and an aq. metallic nitrate soln. contg. metal ions with fuel and allowing the resultant mixture to self-ignite. CONSTITUTION: Fine particles of one or more kinds of metal oxides contg. no nitrate and an aq. metallic nitrate soln. contg. ions of one or more kinds of metals and an excess of nitrate ions over the stoichiometric ratio to the metal ions are mixed with ≥3C water-soluble amino acid as fuel so as to regulate the ratio of the amino acid to the metal ions to 2-4 and the ratio of the amino acid to the nitrate ions to 0.125-0.9 and the resultant mixture is allowed to self-ignite by heating.
