Abstract:Zro2(3Y) precursor was prepared via hydrous-zirconia which was Y(OH)3-coated preparedby microwave heating coated with Y(OH)3. The surfaCes of Al2O3, nanometer SiC and Y(OH)3coated hydrous-zirconia particles were modified with PMAA-NH4, so that three kinds of periclesin aqueous suspensions had the same charge and highly dispersed state at PH=9.0. Finally, ahighly dispersed and uniformly mixed suspension of Al2O3-SiC-ZrO2(3Y) precursor was obtainedfrom miting three kinds of single suspension.
Keywords:colloidal behaviour  surfaCe modification  highly dispersed suspension  uniformlymixed suspension
