Document Type and Number:
WIPO Patent Application WO/2014/171220
Kind Code:
A1
Abstract:
Provided is a method for producing a complex oxide-coated metal powder coated in a highly uniform manner by a complex oxide. This production method involves a first step for coating a metal powder with a metal oxide by means of a hydrolysis reaction of a water-soluble metal compound in the presence of an aqueous medium, and second step for transforming the metal oxide into a complex oxide. In the first step, by adding, to a slurry comprising a metal powder dispersed in a solvent which includes at least water, a water-soluble metal compound which includes a tetravalent metal element and is soluble in the solvent and precipitating a metal oxide including the tetravalent metal element, a slurry of a metal oxide-coated metal powder is obtained in which the metal oxide coats at least a portion of the surface of the metal powder. In the second step, a complex oxide-coated metal powder is obtained by adding a solution or powder including at least one divalent element to the slurry of the metal oxide-coated metal powder and reacting the divalent element with the metal oxide present on the surface of the metal powder in the metal oxide-coated metal powder.
