Silicon compound-coated metal fine particles, composition containing silicon compound-coated metal fine particles, and method for producing silicon compound-coated metal fine particles

摘要

The present invention is a silicon compound-coated metal fine particle in which at least a part of the surface of a metal fine particle comprising at least one metal element or metalloid element is coated with a silicon compound, and Si— contained in the silicon compound-coated metal fine particle The present invention relates to silicon compound-coated metal fine particles, wherein the OH bond ratio is controlled to be 0.1% or more and 70% or less. According to the present invention, silicon compound-coated metal fine particles whose properties such as dispersibility are controlled by controlling the ratio of Si-OH bonds or the ratio of Si-OH bonds / Si-O bonds contained in the silicon compound-coated metal fine particles. Can provide. By controlling the Si—OH bond ratio or the Si—OH bond / Si—O bond ratio, the silicon compound-coated metal fine particles can be used more diversely and have the desired characteristics than the conventional ones. The exact composition can be easily designed.
