PURPOSE:To obtain the title molded article having uniform density distribution of the interior of molded article, no anistotropy in shrinkage in sintering and high dimensional accuracy by subjecting a ceramic raw material for molding consisting of acrylic resin, water and inorganic powder to dry molding. CONSTITUTION:Inorganic powder (e.g., alumina) is blended with 4-20vol.% acrylic resin and 20-45vol.% water and mixed by a ball mill of wet type to give slurry, which is spray-dried to give a ceramic raw material for wet molding. Then the raw material is subjected to dry molding such as pressing method of hydrostatic pressure, monoaxial hydraulic molding or mechanical press molding. |
