The Effect of Processing Additives on Dispersion and Rheological Properties of Freeze Casting Alumina/Zirconia and Mullite/Zirconia Slurries

Abstract:

Freeze casting is a useful forming technique to produce complex-shaped ceramic parts. In order to optimize freeze casting slurries, several processing additives are usually employed. Therefore, the relationships between additives and suspension characteristic should be understood. The effects of incorporating processing additives on dispersion and viscosity functions of aqueous alumina/zirconia and mullite/zirconia suspensions have been investigated.
