Abstract
Multilayer ceramic capacitors (MLCCs) are essential components in pulsed power systems (PPS) with high charging and discharging capacity for energy storage applications. Yttrium oxide (Y2O3)–doped barium titanate (BaTiO3) (BTY) ceramics with a chemical formula of 60 BaO + (40-x) TiO2 + x Y2O3 (x = 2, 8 and 15) have been synthesized by usual solid state reaction process. These ceramics are analyzed by XRD, FTIR and SEM techniques. The crystalline nature of the undoped BaTiO3 (BT) and Y2O3 doped ceramics were confirmed by XRD analysis. In addition, a doublet peak at 30.2° has been shifted to lower angles as the concentration of Y3+ ions increases. The functional groups of these BT and BTY2 ceramics were investigated using FTIR analysis. Morphological studies were performed through scanning electron microscopy (SEM), revealing the average particle size of BT 331 nm and BTY2 136 nm from Image-J software.
