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.
期刊介绍:
Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications.
Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques.
Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals.
Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review.
The Journal is owned by the Korean Physical Society.
