Three cylindrical plaster molds were fabricated from the slurries having water-to-plaster mass ratios of 0.55, 0.63 and 1, and designated as the 55% -mold, 63% -mold and 100% -mold. The 55%, 63% and 100% -molds were characterized by low p_ and low K_m, high p_ and low K_m, and lowp_ and high K_m, respectively. Casting rate at an early stage increased with increasing p_ x K_m or K_m, and average bulk density of cast body increased with increasing p_. Local green density increased from the center toward the wall of mold because of consolidation of the compressible cake. High p_ x K_m and low p_ enhanced percolation effect, and resulted in remarkable segregation of fine particles near the mold wall. Green body with a high relative density of 66.3% and a homogeneous density distribution was obtained from the 63%-mold showing high p_ and low K_m., application/pdf}, pages = {510--516}, title = {高濃度アルミナスラリーの鋳込み成形に及ぼすセッコウ型特性の影響}, volume = {104}, year = {1996}, yomi = {タカハシ, ミノル} }
