Summary:High-temperature structural ceramics have increasingly attracted scientists’ attention in the area of modern science and technology due to their excellent properties of corrosion-resistance, wear-resistance and high-temperature resistance. But their low reliability limits their application in practice. In this note, AE signals of high-temperature structural ceramics under static fatigue were picked up by AE transducer and the relation between AE signals and crack growth in structural ceramics was studied. The results show that the AE rate of structural ceramics has
