摘要 |
Provided is a piezoelectric material having high Curie temperature, high insulation property, and high piezoelectric performance, the piezoelectric material including a perovskite-type metal oxide represented by the general formula (1): xBaTiO3-yBiFeO3-zBi(M0.5Ti0.5)O3, where M represents at least one kind of element selected from the group consisting of Mg, Ni, and Zn, x represents a value satisfying 0.25≦x≦0.75, y represents a value satisfying 0.15≦y≦0.73, and z represents a value satisfying 0.02≦z≦0.60, provided that x+y+z=1 is satisfied in which the perovskite-type metal oxide contains V, and content of the V is 0.0005 mol or larger and 0.0050 mol or smaller with respect to 1 mol of the perovskite-type metal oxide. In addition, provided are a piezoelectric element, a liquid discharge head, an ultrasonic motor, and a dust removing device, which use the piezoelectric material. |
