Abstract
Effects of E$_2$O$_3$. HO$_2$O$_3$ and Dy$_2$O$_3$ addition on dielectric properties of non-reducible BaTiO$_3$ based X7R dielectrics with Ni electrode have been studied in a reduced atmosphere. As the content of rare-earth with E$_2$O$_3$. HO$_2$O$_3$, Dy$_2$O$_3$ was less than 3wt%, The TCC(Temperature Capacitance Change) and insulation resistance characteristics were improved by compensate the oxygen vacancies due to occupy either the Ba or Ti site. We developed the composition of X7R (EIA standard) for higher capacitance MLCC which had high reliability electric properties by the addition of Er ion into BaTiO$_3$ + MgO + Y2O$_3$ + MnO + (Ba$\sub$0.4/Ca$\sub$0.6/)SiO$_3$ composition.
