SPINEL-TYPE COMPOSITE OXIDE PARTICLES AND METHOD FOR PRODUCING SAME, RESIN COMPOSITION CONTAINING SPINEL-TYPE COMPOSITE OXIDE PARTICLES, AND MOLDED ARTICLE

摘要

Spinel-type composite oxide particles each containing a metal atom, an aluminum atom, an oxygen atom and a molybdenum atom, said spinel-type composite oxide particles being characterized in that the metal atom is a metal atom selected from the group consisting of a zinc atom, a cobalt atom and a strontium atom and has a [111] plane crystallite diameter of 100 nm or more. A method for producing the spinel-type composite oxide particles includes: step (1) of firing a first mixture containing a molybdenum compound and a metal atom-containing compound or a first mixture containing a molybdenum compound, a metal atom-containing compound and an aluminum compound to prepare an intermediate; and step (2) of firing a second mixture containing the intermediate or a second mixture containing the intermediate and an aluminum compound at a temperature higher than a temperature selected in step (1).
