Abstract

The problem addressed by the present invention is providing a method for manufacturing fine grains. At least two fluids to be processed, a starting material fluid that contains a starting substance and a processing fluid that contains a substance for processing the starting substance are mixed in a thin film fluid formed between at least two surfaces for processing that are disposed so as to face each other, that can approach and separate from each other and at least one of which rotates relative to the other, and fine particles of the starting substance that is processed are obtained. At this time, the proportion of the fine particles of the starting substance which has been processed that coalesce with each other is controlled by controlling the circumferential speed of the rotation in a confluence section in which the starting material fluid and processing fluid flow together.

Description

technical field [0001] The present invention relates to a method for producing microparticles. Background technique [0002] In recent years, fine particles have been widely used in various fields such as optical materials, magnetic materials, conductive materials, electronic materials, functional ceramics, fluorescent materials, catalyst materials, and chemical materials. For example, fine particles of metals, metal oxides, composite materials, and the like are expected to be materials that dramatically improve optical, electromagnetic, and mechanical properties. In addition, there are great expectations for new properties such as ultra-high functionality and the presentation of new properties due to the quantum size effect of micronization. However, the above-mentioned various characteristics are closely related to the particle diameter, and therefore, not only the simple synthesis of fine particles but also the precise control of the particle diameter of the fine particl...
