ABSTRACT:
There is provided an acidic zirconia sol having compatibility of particle properties and binding properties, and a production method of the same. The acidic zirconia sol includes zirconia particles (a) having a particle diameter ranging from 20 to 300 nm in a content of 90 to 50% by mass, based on the mass of all zirconia particles, and zirconia particles (b) having a particle diameter of less than 20 nm in a content of 10 to 50% by mass, based on the mass of all zirconia particles.
