Producing ceramic molded body comprises producing a dispersion of ceramic powder and solvent for polysulfone, adding a mixture of solvent and polysulfone, subjecting the dispersion to molding, and sintering the molded body

摘要

Reproducible production of ceramic molded body comprises: (a) producing a dispersion comprising ceramic powder and a solvent for polysulfone; (b) adding a mixture comprising the solvent and polysulfone to the dispersion; (c) subjecting the dispersion having a pasty consistency to molding process; (d) immersing or wetting the obtained molded body in a solvent contained in the dispersion, in which the polysulfone is not soluble, to obtain solvent-free molded body; and (e) pyrolytically driving out the contained organic components by heat treatment and sintering the molded body. Reproducible production of ceramic molded body comprises: (a) producing a dispersion comprising ceramic powder and a solvent for polysulfone; (b) adding the dispersion to a mixture comprising the solvent and polysulfone, and adjusting the quantity of polysulfone to = 1 mass% and the quantity of ceramic powder to at least 85 mass% in the dispersion; (c) subjecting the dispersion having a pasty consistency to molding process; (d) immersing or wetting the obtained molded body in a solvent contained in the dispersion, in which the polysulfone is not soluble, to obtain solvent-free molded body; and (e) pyrolytically driving out the contained organic components by heat treatment and sintering the molded body.
