ABSTRACT:
A slurry for molding an article is provided wherein a source powder including at least one of a ceramic powder and a metal powder is dispersed, introduced into a forming mold, cured in the forming mold to form the molded article, and at least a part of the forming mold is degraded or dissolved in releasing the molded article from the forming mold. The major components of the slurry include the source powder, a dispersion medium and a gellifying agent, wherein the dispersion medium and the gellifying agent each contain an organic compound having a reactive functional group such that the slurry is cured by a reaction between the organic compound in the dispersion medium and the organic compound in the gellifying agent.
