Title:

METHOD FOR PRODUCING ALUMINUM-CONTAINING PARTICLES

Document Type and Number:

WIPO Patent Application WO/2022/118824

Kind Code:

A1

Abstract:

A method for producing particles in which mixed particles are obtained by mixing particles to be treated that include a heavy metal having a specific gravity of 4 or more, an aluminum source, an activator including a halide, and a sintering-preventing agent, the mixed particles are heated and the particles to be treated are calorized by using gaps between sintering-preventing agent portions formed by the sintering-preventing agent to obtain a treated mixture including aluminum-infiltrated particles, and the sintering-preventing agent is removed from the treated mixture to recover the aluminum-infiltrated particles.
