Abstract
The parameters affecting the structural and physical properties of the material depends upon its method of preparation. The solid-state synthesis is a widely used commercial method due to its environmental stability, low-cost and large-scale production. This article describes the preparation of lead-free potassium bismuth titanate (KBT) ceramics by the conventional solid-state route. The effect of calcination temperature on the structural and electrical properties of KBT ceramics is studied systematically. The crystal structure and phase confirmation are analysed by using the X-ray diffraction technique. Raman spectroscopy analysis suggests that KBT ceramic has a better crystalline and perovskite structure. Dielectric study shows the diffusive phase transition behaviour of the material revealing its usage for high-temperature applications. Ferroelectric behaviour is confirmed by P–E loop tracer curve at different electric fields. The leakage current density decreases with the rise in calcination temperature and reveals linear ohmic conduction mechanism at higher electric fields.
