Estimating the term…
An object of the present invention is to provide a dispersion of a zirconium element-containing metal oxide having high transparency and low viscosity even at high concentration. The present invention relates to a method of producing a zirconium element-containing metal oxide dispersion, and the production method includes a step of heating a slurry containing a zirconium element-containing compound as a metal element-containing compound to perform a hydrothermal reaction, in which the heating in the hydrothermal reaction step is performed at a temperature rising rate of 90° C./hour or more.
A method of producing a zirconium element-containing metal oxide dispersion, the method comprising a step of heating a slurry containing a zirconium element-containing compound as a metal element-containing compound to perform a hydrothermal reaction,
A zirconium element-containing metal oxide dispersion having a transmittance of light at a wavelength of 550 nm of 70% or more and a viscosity of 25 mPa·s or less in a form of a 48 wt % aqueous dispersion.
