摘要

SrTiO3 ceramics were synthesized by hot-press sintering Na-coated semiconducting SrTiO3 powders. The chemical and electrical characteristics of the grain boundary of the ceramics were investigated, and their relations were discussed in terms of process parameters such as sintering time. A systematic variation in the electrical characteristics of the grain boundary with process parameters was observed; it indicates that this synthesis method can be used for fine control over the chemical and electrical properties of the semiconducting ceramics.
