A non-equivalent co-doped strategy to improve the electrical properties of piezoelectric ceramics

A non-equivalent co-doped strategy to improve the electrical properties of piezoelectric ceramics- In the field of aerospace, a high-temperature piezoelectric vibration sensor is one of the few key devices that can be monitored in a high-temperature and harsh environment, so it is particularly urgent to develop high performance high-temperature piezoelectric ceramics as the core component of this kind of sensor. Bi4Ti3O12 (BIT), as one vital type of bismuth layered structure ferroelectrics (BLSFs), has great application prospects in high-temperature environments due to its excellent TC of 675 ℃.
