BORIDE PARTICLES, BORIDE PARTICLE PRODUCTION METHOD, AND BORIDE PARTICLE DISPERSION

摘要

PROBLEM TO BE SOLVED: To provide boride particles that are highly transparent to light in the visible region and excellent in heat ray shielding properties.SOLUTION: The boride particles are represented by the general formula XAB, where X includes one or more metal elements selected from alkaline earth metal elements, zirconium (Zr) and rare earth elements including yttrium (Y); A includes one or more metal elements selected from In, Ga and Tl; and y and m satisfy 0.0001≤y≤0.2 and 5.2≤m≤6.5.SELECTED DRAWING: Figure 1
