Core-shell structured particles and their manufacturing methods

Abstract

This invention provides a core-shell structured particle possessing insulating and thermally conductive properties, and a method for manufacturing the same. The core-shell structured particle comprises a core composed of metal particles and a shell covering the surface of the core. The shell is composed of an inorganic insulator and does not contain adhesive resin. The inorganic insulator serving as the shell comprises boron nitride and a fibrous metal compound. Furthermore, copper particles can be used as the metal particles, and fibrous alumina can be used as the fibrous metal compound. Moreover, the core-shell structured particle can be manufactured by using an aqueous slurry containing boron nitride and fibrous alumina to coat the copper particles with boron nitride and fibrous alumina. none
