Title:
BISMUTH SULFIDE PARTICLES, METHOD FOR PRODUCING SAME, AND APPLICATION OF SAME
Document Type and Number:
WIPO Patent Application WO/2022/210032
Kind Code:
A1
Abstract:
The present invention addresses the problem of realizing bismuth sulfide which readily reflects infrared light and which has a degree of blackness that is equal to or greater than that of carbon black. The present invention pertains to bismuth sulfide particles which include aggregated secondary particles in which primary particles are aggregated, and in which the cumulative 50% diameter (D1) in a cumulative volume distribution, as measured by a laser diffraction/scattering particle size distribution measuring device is 0.2 μm to 10 μm, inclusive. Included is a step in which a bismuth compound and a sulfur compound are heated at 30℃ to 100℃, inclusive, in a dispersion medium in the presence of a protective agent.
