| Abstract: | LiTaO3/Al2O3 ceramics composites have wide development and application prospect. Based on the second phase LiTaO3 fracture behavior and toughening mechanism, the paper probed into LiTaO3/Al2O3 ceramics composite material preparation technology of different toughening mechanism. The result shows that particle LiTaO3 piezoelectric ceramic can stably coexist with Al2O3 substrate , and can better play toughening role. To get the best performance of suitable techniques of preparation is current research trend. |
