Silicon-coated metal fine particles, silicon compound-coated metal fine particles and their manufacturing methods

摘要

PROBLEM TO BE SOLVED: To provide a method for producing silicon-coated metal fine particles or silicon compound-coated metal fine particles, which can be stably supplied with low energy and resource saving, and silicon-coated metal fine particles or silicon compound-coated metal fine particles. SOLUTION: A silicon-coated metal fine particle in which at least a part of the surface of a metal fine particle composed of at least one metal element or a metalloid element is coated with silicon, and the silicon-coated metal fine particle is a precursor of the metal fine particle. It is characterized in that at least a part of the surface of the precursor fine particles including the body is coated with a silicon compound, or the silicon-doped precursor fine particles containing the precursor of the metal fine particles are reduced.
