Abstract
Provided is a novel tantalate dispersion containing no hardly-volatile organic component and having high dispersibility in water, the tantalate dispersion containing tantalum or/and tantalate and amine in water, the tantalate dispersion having an intensity ratio (5.5°/29°) of an intensity at 2θ=5.5° to an intensity at 2θ=29° being 1.00 or more in an X-ray diffraction pattern obtained by subjecting a powder obtained by drying the tantalate dispersion to powder X-ray diffraction measurement using CuKα rays.
