Abstract
A method for producing a powder-molded body is provided, including the steps of casting a slurry containing a powder of at least one of a ceramic and a metal, and organic dispersion medium, and a gelling agent into a mold, and solidifying the slurry by gelling the slurry to obtain a molded body. The slurry is solidified by chemically bonding an organic dispersion medium having reactive functional groups and a gelling agent. The method is capable of improving gelling (solidification) efficiency and obtaining a molded body having a high density, a small firing shrinkage, and high shape precision, and which hardly experiences cracks during drying and firing.
