Two Stage Sintering of Barium Titanate Ceramic
Abstract
The potential of a two-stage sintering technique as a low-cost and simple ceramic
fabrication to obtain highly dense and pure barium titanate ceramics with a small grain size was
demonstrated in this study. Effects of designed sintering conditions on phase formation,
densification, microstructure, and dielectric properties of the BaTiO3 ceramics were examined via Xray
diffraction (XRD), Archimedes method, scanning electron microscopy (SEM) and dielectric measurements, respectively. It has been found that, under suitable two-stage sintering conditions,
dense perovskite BT ceramics with fine grains and good electrical properties can be achieved.
