    摘要： The problem addressed by the present invention is to provide a method for producing microparticles. Provided is a method that is for producing microparticles and that is characterized by containing at least the the following two steps: (I) a step for preparing a microparticle starting material solution by dissolving at least one type of microparticle starting material in a solvent using high speed stirring or ultrasonic waves, and (II) a step for precipitating microparticles by mixing the microparticle starting material solution and at least one type of precipitation solvent for precipitating the microparticle starting material in a thin film fluid formed between at least two processing surfaces that are disposed facing each other, are able to approach/ separate from each other, and of which at least one rotates relative to the others.

    摘要： The present invention addresses the problem of providing producing processes for garnet precursor microparticles (a precursor for microparticles of garnet structure) and microparticles of garnet structure. One of the processing processes comprises mixing ions of at least two elements with a basic substances that contain the at least two elements. The thin-film fluid is formed between at least two processing surfaces which are approachably and separably arranged facing each other with at least one of the processing surfaces rotating relative to the other. In the processing process, the precipitated microparticles are garnet precursor microparticles, and the molar ratio between the at least two elements in the garnet precursor microparticles is regulated by controlling the pH of the thin-film fluid after the mixing. Microparticles of garnet structure can be obtained by subjecting the garnet precursor microparticles to heat treatment. Specifically, the yttrium/ aluminum molar ratio of yttrium-aluminum-garnet (YAG) precursor microparticles is regulated by controlling the pH of the thin-film fluid after the mixing, YAG being an example of the crystal of garnet structure.

    摘要： The present invention addresses the problem of providing a method for producing microparticles having a controlled crystallite diameter. At least two types of fluids to be processed; i.e., a raw material fluid containing a substance to be separated, and a separating fluid containing a substance for causing separation of the substance to be separated, are mixed in a thin film fluid formed between at least two processing surfaces which are approachably and separably disposed facing each other. At least one processing surface rotates relative to the other, and the substance to be separated giving a controlled crystallite diameter is caused to separate. At this time, specific conditions related to the fluid to be processed introduced between the processing surfaces are varied to control the crystallite diameter of the substance to be separated. The specific conditions are at least two conditions selected from the group consisting of: the type of substance to be separated included in the raw material fluid and/ or substance included in the separating fluid; the concentration of the substance to be separated included in the raw material fluid and/ or substance included in the separating fluid; the pH of the raw material fluid and / or separating material fluid; the introduction temperature of the raw material fluid and/ or separating fluid; and the introduction velocity of the raw material fluid and/ or separating fluid.
