| Abstract | Bi-doped Sr0.7Ba0.3TiO3 ceramics sintered at different temperatures were studied by analytical electron microscopy. Grain boundaries (GBs) with discrete Bi nano-precipitates (NP) were observed in both samples sintered at 1170ºC and 1190ºC. Dopants’ solutions as well as their segregations to GB were analyzed quantitatively to reveal the origin of NP. NP at GB contributed to the high dielectric constants of the materials. |
