The piezoelectric effect and inverse piezoelectric effect of piezoelectric crystals have been widely used in the field of science and technology. The surface acoustic device is prepared with piezoelectric crystal as the substrate is easy to realize the miniaturization of the device due to its excellent electrical properties, and is widely used in communications, radar, navigation, and so on. In recent years, lanthanum gallium silicate structure crystals have been widely used in surface acoustic waves, bulk surface wave filters, and sensors.
