Tailoring the tetragonal distortion to obtain high Curie temperature and large piezoelectric properties in BiFeO3-PbTiO3-BaTiO3 solid solutions
Source abstract
Abstract
Abstract High-temperature and high-performance piezoelectric ceramics were urgently required in the oil drilling, automotive and aerospace industries. Here, a solid solution of (0.67-x)BiFeO3-0.33PbTiO3-xBaTiO3 (BF-PT-BT) with dominant tetragonal phase was fabricated by a solid-state reaction method. The tetragonal distortion of BF-PT-BT ceramics from 1.152 to 1.050 is adjusted by changing the BT content. It is found that the c/a ratio has significant influence on the Curie temperature and electric properties. With the decrease of the tetragonal distortion, the coercive field and Curie temperature decrease, while both the dielectric and piezoelectric properties are enhanced significantly. When the c/a ratio range from 1.118 to 1.050, the piezoelectric coefficient d33 and the Curie temperature both depends linearly on the c/a ratio by relations of 106+(12.6/0.01)*(variation of c/a ratio) pC/N, and 600-(15.5/0.01)*(variation of c/a ratio) °C, respectively. The high Cuire temperature (>495 °C) and large piezoelectric coefficient (>106 pC/N) may have great potential for piezoelectric applications.
