In the study of microwave sintering of BaTiO〓 PTC ceramics, when the applied microwave power are above than a certain value, the abnormal axial shrinkage of the sintered sample will occur, by the analysis of SEM and XRD, it is found the microstructure and phase are different with conventionally sintered sample, the reason for this phenomenon is due to orientational grain growth by the action of electric field in the microwave sintering process.
