摘要: 采用微波加热水解氧氯化锆及醇水混合液体,制得ZrO_2前驱物——纳米水合氧化锆溶胶。讨论了反应液体中氧氯化锆浓度和醇/水比对生成物平均粒度及其分布的影响;得出了采用聚甲基丙烯酸铵作为电空间稳定剂的亚微米级氧化铝水悬浮液的稳定条件;阐述了溶胶-悬浮液混合制备复合陶瓷的工艺过程。

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.
