Piezoelectric material, piezoelectric element, liquid ejecting head, liquid ejecting apparatus, ultrasonic sensor, piezoelectric motor, and power generator
A piezoelectric material contains a first component that is a rhombohedral crystal and that is configured to have a complex oxide with a perovskite structure and Curie temperature Tc1, a second component that is a crystal other than a rhombohedral crystal and that is configured to have a complex oxide with a perovskite structure and Curie temperature e Tc2, and a third component that is a rhombohedral crystal and that is configured to have a complex oxide with a perovskite structure and Curie temperature Tc3 different from the first component, and in which Tc2 is higher than Tc1, Tc3 is equal to or higher than Tc2, and a value of (0.1×Tc1+0.9×Tc2) is equal to or lower than 280° C.
