초록
To understand the contribution of rare earth additive material (Dy2O3) in BaTiO3-MgO-Mn3O4-BaCO3-SiO2-xwt%Dy2O3-based (hereafter BT-based) ceramics (0.3≤×≤1.2) for multilayer ceramic capacitors (hereafter MLCC) prepared using BT based powder and their properties were investigated electrical and structural properties. The BT grain size and dielectric constant of Dy-doped samples was found to increase with increasing Dy2O3 content. In particular, the 0.6 wt%Dy2O3 doped sample shows high resistance capacitance (RC) values of 2500 Ω • F, dielectric constant of 3600, dielectric loss of 1.4%, stable temperature coefficient of capacitance (TCC). These results indicate that 0.6 wt%Dy2O3 doped BT-based ceramic is a promising candidate material for superior X5R type MLCC.
