Abstract:
A piezoelectric ceramic which comprises three types of perovskite structure compounds having different crystal structures. The three types of compounds may be present in a state of a complete solid solution or a state being not a solid solution. The three types of perovskite structure compounds are preferably a compound having a rhombohedral perovskite structure such as (Na0.5Bi0.5)TiO3, a compound having a tetragonal perovskite structure such as BaTiO3 and (K0.5Bi0.5)TiO3 and a compound having an orthorhombic perovskite structure such as NaNbO3, KNbO3 and CaTiO3, or are preferably a compound having a rhombohedral perovskite structure, a compound having a tetragonal perovskite structure and a compound having a cubic perovskite structure such as SrTiO3. The piezoelectric ceramic exhibits improved piezoelectric characteristics due to the presence of three types of perovskite structure compounds having different crystal structures.
Abstract:
The present disclosure is drawn to an oxygen conducting bismuth perovskite material, a method of conducting oxygen through the material, and a method of making the material. The oxygen conducting bismuth perovskite material can include two components selected from the group consisting of NBT, KBT, BZT, BMT, and BNiT. The material can also have a sufficient degree of non-stoichiometry to provide oxygen vacancies to conduct oxide ions.
