Abstract

A direct casting method of aqueous acidic high solids loading alumina and zirconia slurries stabilized by zirconium acetate (Zr-Ac) has been reported. In this study, we investigated the effects of Zr-Ac and pH on the fluidities of alumina-zirconia slurries and we found the optimum conditions of the thickening for these slurries. Complex near-net shaped alumina-zirconia composites have been obtained by the urea-urease enzyme reaction.
