ABSTRACT:
A production method of an alkaline zirconia sol including: a process (I) in which an alkaline zirconia sol (A) is mixed with a basic zirconium carbonate salt (B1), the alkaline zirconia sol (A) being obtained by: a sub-process (i) in which a zirconium salt (B2) is heated at 60 to 110° C. in an aqueous medium containing a carbonate salt of quaternary ammonium; and a sub-process (ii) in which a hydrothermal treatment is performed at 110 to 250° C. following the sub-process (i).
