Piezoelectric ceramics, manufacturing method for piezoelectric ceramics, piezoelectric element, liquid discharge head, liquid discharge apparatus, ultrasonic motor, optical apparatus, vibration generator, dust removing device, imaging apparatus, and electronic apparatus
Provided is a piezoelectric ceramics that can achieve both high piezoelectric performance and a high Curie temperature. Also provided are a piezoelectric element, a liquid discharge head, an ultrasonic motor, and a dust removing device, which use the piezoelectric ceramics. The piezoelectric ceramics include a perovskite-type metal oxide expressed by a general formula (1): xBaTiO3-yBiFeO3-zBi(M0.5Ti0.5)O3, where M represents at least one type of element selected from the group consisting of Mg and Ni, x satisfies 0.40≰x≰0.80, y satisfies 0≰y≰0.30, z satisfies 0.05≰z≰0.60, and x+y+z=1 is satisfied, and are oriented in a (111) plane in a pseudocubic expression.
