METHOD FOR PRODUCING PARTICLE DISPERSION, AND METHOD FOR PRODUCING OXIDE SEMICONDUCTOR PARTICLE

摘要

PROBLEM TO BE SOLVED: To impart electric conductivity, dispersibility, dispersion stability, transparency, precipitation preventability and the like to a particle or to improve these properties of the particle by an extremely simple method.SOLUTION: A method for producing a particle dispersion comprises steps of; firstly producing a simple substance or preparing a mixture 12 by using one or more compounds selected from the group consisting of organic metal compounds and organic semimetal compounds; and secondly irradiating the simple substance and the mixture with a microwave in a predetermined atmosphere to disperse particles and produce such a colloidal particle dispersion 14 that particles are not precipitated for two weeks or more and a colloid-peculiar ink-like state is kept. An organic component of the organic metal compounds or the organic semimetal compounds is one or more compounds selected from the group consisting of organic acids and amines and the organic acids are photopolymerizable compounds.
