Document Type and Number:
WIPO Patent Application WO/2021/153693
Kind Code:
A1
Abstract:
Provided is an electromagnetic wave absorbing particle dispersion comprising a solid medium and electromagnetic wave absorbing particles which contain a cesium tungsten oxide that is expressed by the general formula CsxW1-yO3-z (0.2 ≤ x ≤ 0.4, 0 < y ≤ 0.4, 0 < z ≤ 0.46) and has an orthorhombic or hexagonal crystal structure, wherein the electromagnetic wave absorbing particles are dispersed in the solid medium.
