Table 2 Composition analyses for BiT-Bi and BiT-La. EDS data for grain composition were obtained by surface scans on five entire grains, and the mean value and standard deviation were listed.
Sample | elements | grain | Point 2 at grain boundary | theoretical composition |

Ti (at. %) | 15.20(0.46) | 13.08 | 15.54 | |
BiT-La (Bi4Ti3O12 • 0.06La2O3) | O (at. %) | 63.34(0.45) | 65.24 | 63.11 |
