PURPOSE:To achieve reduction of dissolution and hydration of ceramics by a method wherein aqueous suspension of ceramics is dispersed by adding a specific wt.% of a non-polymeric organic compound having a specific functional group to the aqueous ceramic suspension. CONSTITUTION:A non-polymeric organic compound which has at least one hydroxyl group and functional groups selected from the group consisting of carboxyl group, carboxylate, sulfonic acid, sulfonate, phosphoric acid, phosphate, an amine, and a quaternary amine salt is added to an aqueous ceramic suspension. Its added amount is 0.1-5.0wt.% based on dry weight of the ceramics. Thereby, colloidal ceramic particles are stabilized and at the same time, dissolution and/or hydration velocity of the particles can be reduced. |
