Piezoelectric material, piezoelectric element, liquid discharge head, ultrasonic motor, and dust cleaning device
A piezoelectric material including a barium bismuth niobate-based tungsten bronze structure metal oxide having a high degree of orientation is provided. A piezoelectric element, a liquid discharge head, an ultrasonic motor, and a dust cleaning device including the piezoelectric material are also provided. A piezoelectric material includes a tungsten bronze structure metal oxide that includes metal elements which are barium, bismuth, and niobium, and tungsten. The metal elements satisfy following conditions on a molar basis: when Ba/Nb=a, 0.30≰a≰0.40, and when Bi/Nb=b, 0.012≰b≰0.084. The tungsten content on a metal basis is 0.40 to 3.00 parts by weight relative to 100 parts by weight of the tungsten bronze structure metal oxide. The tungsten bronze structure metal oxide has a c-axis orientation.
