Abstract:
Ca 1-3xLn 2xTiO 3 (Ln=La, Nd, Sm; x=0.13, 0.20) ceramics were investigated systematically to dicuss the influences of sintering temperature, compositions, Ln 3+ ions on its sintering property, crystal structure and microstructure. The results show that the dense ceramics were obtained in the sintering temperature range of 1300∼1350 °C and the relative density reached over 97%. Sintering temperature was 50∼150 °C lower than previous reports. Single orthogonal perovskite structure phase was formed except that a little secondary phase Sm 2Ti 2O 7 was detected by XRD analysis when x=0.20 and Ln=Sm. The growth pattern of Ca 1-3xLn 2xTiO 3 grains was terracing growth. © (2012) Trans Tech Publications.
