| Abstract: | Nano-zirconia has been prepared by homogeneous co-precipitation method in the rotating packed bed(RPB) using ammonia and zirconium oxychloride as the materials.The precursor and powder were characterized by means of XRD,TEM and BET.The influences of rotating-speed,the dehydration process with alcohol and the heating-temperature on granularity,dispersion and crystalline type of nano-zirconia were studied.The results show that the tetragonal nano-ZrO2 with less hard-agglomeration and narrow distribution can b... |
