NONSTOICHIOMETRIC OXIDE PARTICLE, AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide high purity nanosized nonstoichiometric oxide particles, and a manufacturing method capable of manufacturing nanosized nonstoichiometric oxide particles in a short time using thermal plasma.SOLUTION: A manufacturing method of nonstoichiometric oxide particles includes a step for preparing metal oxide powder and at least one kind of powder among metal powder of a metal element constituting the metal oxide powder, powder of a compound of an element other than oxygen and the metal element, and powder of a nonstoichiometric oxide of the metal element; and a step for supplying the metal oxide powder and the at least one kind of powder into thermal plasma flame.
