Abstract
A latent heat storage body microcapsule includes a core including gallium or gallium alloy; and a shell covering the core and including gallium oxide. A method for producing the same includes a particle-forming step of forming gallium or an alloy of gallium in a liquid state into particles; a water treatment step of heating the particles in distilled water to form a gallium hydrate on a surface of each of the particles; and an oxidation treatment step of oxidizing the gallium hydrate to form a shell including gallium oxide. The method includes a particle-forming step of forming gallium or an alloy of gallium in a liquid state into particles; a cooling step of cooling the particles to a solid state; and a pH treatment step of immersing the particles in an aqueous solution having a predetermined pH to form a shell including gallium hydrate.
