Problems solved by technology

Due to the low fracture toughness of the piezoelectric ceramic material itself, the performance is unstable, which greatly reduces the reliability of the material, and is limited in practical applications.
For the research on the toughening of piezoelectric ceramics, although the fracture toughness of piezoelectric ceramics can be improved to a certain extent by adding the second phase, but at the same time it will also reduce its piezoelectric performance, so it is necessary to provide a high-voltage electrical Piezoelectric ceramic materials with high performance and high mechanical properties and their preparation methods are of great practical significance
