Abstract

The change in strength of barium titanate/zirconia composite on polarization treatment is evaluated. and the mechanism of this phenomenon is discussed. We have already reported that the bending strength of this composite has increased on longitudinal poling. In this study bending strength of BT/8YSZ composite increased on longitudinal poling and decreases on transverse poling compared with the untreated samples. Both strengthened and weakened specimens tend to return to the almost original strength by heating over Tc of barium titanate.
