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 in a and that is configured to have a complex oxide with a perovskite structure and Curie temperature is set to be 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 is set to be Tc2, and a third component that is a rhombohedral crystal and that is configured to have a complex oxide with a perovskite structure but Curie temperature is set to be 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, a composition near an MPB line is provided in a phase diagram that employs a ratio of the first component to the sum of the first component and the second component (the first component/(the first component+the second component)) for the horizontal axis, and temperature for the vertical axis, and Curie temperature Tc4 of the composition is equal to or higher than 280°C.
