Sodium bismuth titanate-based lead-free ferroelectric ceramic material as well as preparation method and application thereof
The invention discloses a sodium bismuth titanate-based lead-free ferroelectric ceramic material with high remanent polarization and high depolarization temperature, and belongs to the field of functional ceramics. The composition of the ceramic material is (1-x) {(1-z) Bi < 0.5 > Na < 0.5 > (Ti < 1-y > Mn < y >) O < 3-z > BiGaO < 3 >}-xZnO, x is less than or equal to 0.10, 0lt; y is less than or equal to 0.01, 0lt; z < = 0.02. By adjusting the addition amount of ZnO, the remanent polarization intensity and depolarization temperature of the ceramic are improved at the same time, the highest remanent polarization intensity can reach 47.56 [mu] C/cm < 2 >, and the highest depolarization temperature can reach 214 DEG C.
