The present invention provides a method for producing a slurry composition capable of realizing excellent dispersibility in a simple process and maintaining high dispersibility over a long period of time, comprising an inorganic powder, a mixed polyvinyl acetal Adding and mixing the resin (A) and the organic solvent for inorganic dispersion to prepare an inorganic dispersion, adding and mixing the polyvinyl acetal resin (B) and the organic solvent for resin solution to prepare a resin solution, and And a step of adding a resin solution to the inorganic dispersion, wherein the mixed polyvinyl acetal resin (A) has a hydroxyl group content of 18 to 37 mol% and a hydroxyl group content of 28 to 60. The polyvinyl acetal resin (a2) is mol%, and the polyvinyl acetal resin (B) has a degree of polymerization of 800 to 4000, and produces the inorganic dispersion. In the step of, the mixed poly (vinyl acetal) resin (A) is a manufacturing method of a slurry composition to be added to the inorganic powder. |
