Abstract
The present invention provides a method for producing an inorganic particle-containing slurry, by which the number of coarse particles can be sufficiently reduced. The present invention is a method for producing an inorganic particle-containing slurry, which comprises: a step of preparing an inorganic particle dispersion containing inorganic particles and a dispersing medium, and having a pH less than the isoelectric point of the inorganic particles; and a step of adding an alkaline compound to the inorganic particle dispersion in such a manner that the pH does not reach the isoelectric point of the inorganic particles.

A method for producing an inorganic particle-containing slurry, comprising the steps of:
- preparing an inorganic particle dispersion containing an inorganic particle and a dispersing medium, and having a pH less than the isoelectric point of the inorganic particle;
- and
- adding an alkaline compound to the inorganic particle dispersion in such a manner that the pH does not reach the isoelectric point of the inorganic particle to obtain the inorganic particle-containing slurry having a pH in the range of 3.0 or more and less than 6.0,
- wherein the inorganic particle-containing slurry comprises a sugar alcohol.
