Development of alumina mold for slip-casting

Slip-casting is widely used as one of the shaping methods of ceramics. Gypsum molds used for slip-casting are expendables, and industrial wastes after use. In this work, we attempted to develop alumina mold, which are used as substitute for the gypsum molds. Alumina mold also have heat resistance, therefore, it is applicable for a new manufacturing process, where alumina mold and slip-casted green body are fired together without de-molding. Here, we introduce ceramic mold and sintered alumina bodies made by using the mold.
