Manganese-modified BiScO 3-PbTiO 3 piezoelectric ceramic for high-temperature shear mode sensor

Journal Article


Abstract


  • The bismuth-based perovskite solid solution (100-x) BiSc O3 -xPbTi O3 (BSPT) was investigated for use at temperatures up to 400 ��C and above. The high-temperature resistivity, together with dielectric and piezoelectric behaviors of the shear mode for manganese-modified BSPT ceramics near the morphotropic phase boundary composition were studied. The resistivity and time constant were found to be 3�� 107 �� cm and 0.08 s, respectively, at 450 ��C for modified BSPT66. The dielectric constant ��11T and dielectric loss were found to be 1112 and 1%, respectively, at room temperature, showing a Curie temperature at 468 ��C. The electromechanical coupling factor k15 was calculated to be 61%, staying nearly constant up to 440 ��C, expanding the temperature usage range significantly. The properties indicate that the modified BSPT66 material is a promising candidate for high-temperature shear sensor applications. �� 2005 American Institute of Physics.
