    摘要： The present invention includes a method for freeze molding, comprising the steps of: mixing poly(vinyl alcohol) or a modified additive thereof with a material slurry to obtain a mixture; pouring the mixture into a molding die; and subjecting the mixture in a molding die to at least one cycle of cooling and heating so as to obtain a compact. A compact obtained in this method is free from melting and can maintain its configuration even if the compact is kept at a temperature of freezing point or higher. Further, since the method does not require vacuum drying, the compact can easily be dried.

    摘要： A screw for an extruder includes a drive shaft and stirring blades arranged on the drive shaft, and blades among the stirring blades arranged at least part of the drive shaft adjacent to the leading edge of the drive shaft are interrupted blades, each of continuous surfaces of the interrupted blades being less than a full circle about the drive shaft. The screw is capable of effectively preventing problems that characteristics of a compressed material obtained are not unified in each part, resulting in uneven distribution, and discontinuous portions (screw marks) are formed inside the obtained compressed product.

    摘要： 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.
