Piezoelectricity ceramic, sinter, method for manufacturing same, and piezoelectricity ceramic device using same

摘要

The present disclosure provides a piezoelectricity ceramic material. The piezoelectricity ceramic material includes main components that are represented by a general chemical formula of PbZraTib(Nb2/3Ni1/3)1-a-bO3+c%BaW0.5Cu0.5O3 d%SiO2 and satisfy the following condition: 0.1≦a≦0.4, 0.2≦b≦0.5, 0.1≦c≦3, and 0.05≦d≦1. The low-temperature sintering adopted by the present disclosure reduces energy consumption and reduces the volatilization of PbO, which avoids the fluctuation and deviation of the ceramic components, reduces the pollution to then environment caused by volatilization, and reduces the corrosion to the sintering machine as well. Furthermore, the present disclosure provides a piezoelectricity ceramic sinter and a method for processing the same, as well as a piezoelectricity ceramic device. In a multi-layer device, the device cost is greatly reduced.
