MnO 2 doped (Na 0.82 K 0.18 ) 0.5 Bi 0.5 TiO 3 lead-free piezoelectric ceramics were prepared by conventional solidstate reaction process and the effect of MnO 2 addition on the pyroelectric, piezoelectric and dielectric properties were studied. The experiment results showed that the pyroelectric, piezoelectric, and dielectric properties strongly depended on MnO 2 addition in the (Na 0.82 K 0.18 ) 0.5 Bi 0.5 TiO 3 ceramics. Excellent electrical properties were obtained in (Na 0.82 K 0.18 ) 0.5 Bi 0.5 TiO 3 with 0.8 mol% MnO 2 . The large dielectric loss of pure BNT ceramics was significantly reduced, the piezoelectric constant was improved, and it also showed excellent pyroelectric properties when compared with other lead free ceramics, with pyroelectric coefficient p 017 × 10 −4 C/m 2 K and figure of merit F d 06.56×10 −5 Pa −0.5 . With these outstanding pyroelectric properties, the 0.8 mol% MnO 2 doped (Na 0.82 K 0.18 ) 0.5 Bi 0.5 TiO 3 ceramic can be a promising material for pyroelectric sensor applications in future.

0.95 (KXNa1-X) NbO3-0.05 LiSbO3(KNN-LS-X) (X=0.4-0.5) lead-free ceramics were prepared by conventional solid method. The effect of K/Na ratio on the dielectric, piezoelectric, pyroelectric and polymorphic phase transition was studied. The results show that the electrical properties strongly depend on the K/Na ratio. The KNN-LS-X(X=0.45) ceramics exhibit enhanced properties (εr=891.267,d33=222pC/N,Kp=0.43517,Qm=64.72,p=15×10-4C/m2K). Enhanced electrical properties of the KNN-LS-X (X=0.45) ceramics could be attributed to the effect of K/Na ratio modifying the polymorphic orthorhombic-tetragonal phase transition temperature to room temperature, which could make KNN-LS-X (X=0.45) ceramics use as a new ferroelectric sensor.

“…In particular, the perovskites of formula ABO 3 remain interesting because of their multifunctional properties such as: FE properties (non-volatile memories), important permittivities (capacitors), large piezoelectric (PZ) effects (sensors, actuators, etc. ), and important pyroelectric coefficient (infrared detectors) [3][4][5][6][7]. As a result, most researchers are concerned with improving these dielectric properties rather than looking at new syntheses.…”

Polycrystalline samples Ca 0.85−x La x K 0.15−x Ti 0.85 Nb 0.15 O 3 (x = 0 and 0.05) were synthesized by the conventional solid-state reaction method. The X-ray diffraction showed that these compounds crystallized, at room temperature, in the orthorhombic structure with Pbnm space group. The scanning electron microscopy analysis showed a decrease in grain size with the La 3+ substitution rate. Through the diffuse reflectance spectroscopy, we extracted the band gap energy, which decreases with the addition of La 3+ , which implies the improvement of the semiconductor behavior. Filament, a study on the dielectric properties, in the frequency range from 1 kHz to 1 MHz, of our samples, shows that the substitution of calcium and potassium by lanthanum in A site introduced an improvement to these properties and the appearance of a new transition.
