Abstract
From the viewpoint of solving environmental problems, changeover from organic solvent-based system to water-based system in tape casting process has been required. The effects of organic additives on the rheological properties of water-based alumina slurries were investigated. By means of the zeta potential measurement, the optimum content of added dispersant was estimated. Furthermore, precipitation test and viscosity measurement were performed. From these measurements, optimum amounts of dispersant and binder were decided. Well-dispersed and high solid content slurry gave good quality green sheets, and high density sintered bodies were obtained.
