Title:
AQUEOUS DISPERSION AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2012/066909
Kind Code:
A1
Abstract:
An aqueous dispersion according to the present invention comprises particles formed from a compound oxide containing lanthanoid or yttrium and aluminum. The maximum grain size (Dmax) of the particles is 100 nm or less, and the pH of the aqueous dispersion is 1 to 7. Transmittance of the aqueous dispersion in the visible light wavelength region (400 to 800 nm) is ideally 80% or greater. The volume based average grain size (D50) of the particles is ideally 1 to 70 nm. The particles ideally have a garnet structure or perovskite structure.
