| Abstract: | Hydrous - zirconia sol, which is the precursor of ZrO2 nanoparticle, is produced by the hydrolysis of various ZrOCl2 solution with alcohol - water solvent in microwave oven. The concentrations and alcohol - water ratioes in the mother liquor greatly influenced the average size and its distributions of resulting particles. The stability of aqueous suspensions of submicrometer aaaaaaaaaaaa - Al2O3 with PMAA - NH4 as dispersant was discussed. The preparation process of ZrO2(n) - Al2O3 ceramic nanocomposites by mixing sol with aqueous suspension was presented. |
