Abstract

The BaBi₂Nb₂O₉ (BBN) ceramic, calcined at a temperature of 750 °C–950 °C, was fabricated using conventional solid-state reaction method. The higher the calcination temperature, the lower intermediate phases in the raw powders. After the sintering process, a single BBN phase without intermediate phases is formed in all ceramic specimens. However, structural changes such as grain size and XRD peak shift of the (115) plane appear depending on the calcination temperature. The structural and electrical properties of the ceramics calcined at 950 °C shows the largest average grain size and lower dielectric breakdown strength (BDS) value. On the other hand, the ceramics calcined at 750 °C shows the smallest grain size and high dielectric BDS value. This suggests that BBN ceramics calcined at 750 °C have the most beneficial properties as an energy storage device.
