Abstract
The effect of Mn2+ on the temperature coefficient of capacitance (TCC) of TiO2/SiO2-doped BaTiO3 ceramics has been investigated. The experiment has shown that the high temperature peak of TCC exhibited a continuous enhancement when Mn2+ concentration increased and X8R specification was gradually met. The secondary phase Ba2TiSi2O8 was found in all samples. SEM and XRD analyses have proved that Mn2+ could depress the crystallization of TiO2/SiO2 in BaTiO3 ceramics. The microstrain study through MAUD analysis depicted that the high temperature peak of TCC was dependent on the microstrain of samples to a certain extent. The Mn2+ could be a useful dopant for ameliorating the TCC of TiO2/SiO2-doped BaTiO3 ceramics.
