| Abstract: | In this paper the doped BaTiO. powder were synthesized at low temperature, the Y, Sr doped PTC ceramics were prepared. At last, the synthesis process of powders was analysised by DTA and TGA methods, the effect of Y and Sr on crystal size, microstructure, domain and the effect of Ca were analysised by SEM, TEM and EDS methods. |
