| Abstract: | Uniform and fine lead zirconate-titanate crystallites were grown in-situ in gel-glasses successfully.By XRD,SEM and DTA techniques,it is found that the nuclei-controlled crystallization characters in the whole bulk are manifested in the crystallization process of lead zirconate-titanate phases.The tetragonal ZrO_2 microcrystallites of nano-size are considered to be the original crystal nuclei. |
