Perovskite type oxide material, piezoelectric element, liquid discharge head and liquid discharge apparatus using the same, and method of producing perovskite type oxide material

摘要

A perovskite type oxide of a single crystal structure or a uniaxial-oriented crystal structure represented by ABO₃ where site A includes Pb as a main component and site B includes a plurality of elements, wherein the perovskite type oxide includes a plurality of crystal phases selected from the group consisting of tetragonal, rhombohedral, orthorhombic, cubic, pseudo-cubic and monoclinic systems and the plurality of crystal phases are oriented in the direction of 100.
