Large strain response under low field in SrTiO3 modified Bi1/2Na1/2TiO3–LaFeO3piezoceramics
To further reduce the driving field of Bi1/2Na1/2TiO3-based piezoceramics to meet the requirements for real actuators applications, SrTiO3 modified 0.99Bi1/2Na1/2TiO3-0.01LaFeO3 piezoceramics were synthesized. The 0.79Bi1/2Na1/2TiO3-0.01LaFeO3-0.20SrTiO3 provides the large electrostrains of 405 pm/V...

| Summary: | To further reduce the driving field of Bi1/2Na1/2TiO3-based piezoceramics to meet the requirements for real actuators applications, SrTiO3 modified 0.99Bi1/2Na1/2TiO3-0.01LaFeO3 piezoceramics were synthesized. The 0.79Bi1/2Na1/2TiO3-0.01LaFeO3-0.20SrTiO3 provides the large electrostrains of 405 pm/V at 1.7 kV/mm and 565 pm/V at 2 kV/mm, which are triable values for actuator applications in non-textured Bi1/2Na1/2TiO3-based piezoceramics. |
