In2O3-10SnO2陶瓷中In4Sn3O12与富Sn析出相特征
Characteristics of In4Sn3O12and Sn-rich precipitate in In2O3-10SnO2 ceramic
摘要
Abstract
ITO ceramics were prepared using co-precipitation powders which contained 10% SnO2.The samples were sintered at 1600℃for different time in oxygen atmosphere. The phase composition, element distribution and microstructure of ceramics were studied by XRD, EPMA, TEM and SEM. The results show that nanosized Sn-rich phase with body-centered cubic structure precipitatesin In2O3:Sn grains. Meanwhile, In4Sn3O12grains form at triple junctions of In2O3:Sn grains, and precipitate-free zones appear around In2O3:Sn grain boundaries. The sizes and distancesof Sn-rich precipitates in In2O3:Sn grains decrease gradually from grain center to grain boundary. Furthermore, the sizes of In4Sn3O12grains and Sn-rich precipitates as well as the width of precipitate-free zones increase with extension of the holding time.关键词
