酸化物粒子の製造方法
Document Type and Number:
Japanese Patent JP6823771
Kind Code:
B2
Abstract:
The object of the present invention is to provide a method of producing oxide particles, which can improve crystallinity of the obtained oxide particles, more desirably can form single crystal oxide particles stably. The present invention provides a method of producing oxide particles, which comprises at least two fluids to be processed including the first fluid and the second fluid, wherein one of the first fluid and the second fluid is an oxide raw material liquid obtained by mixing at least an oxide particle raw material with a solvent, and the other of the first fluid and the second fluid is an oxide precipitation solvent obtained by mixing at least a basic substance with a solvent, and wherein the method comprises mixing the first fluid and the second fluid in the space between the processing surfaces which are disposed so as to face each other, being capable of approaching to and separating from each other, at least one of which rotates relatively to the other; and discharging the mixed fluid in which the oxide particles are precipitated from the space between the processing surfaces; and wherein the method controls crystallinity of the oxide particles discharged from the space between the processing surfaces, by changing at least one selected from the group consisting of the temperature of the first fluid to be introduced in the space between the processing surfaces, the temperature of the second fluid to be introduced in the space between the processing surfaces, and the temperature of the first fluid and the second fluid at the time of mixing.
