“…Mn ions are often used as dopants in Pb-based materials for mechanical quality factor enhancement and dielectric loss reduction [13,14]. Huang et al [15] used a solid-state reaction method to prepare Mn-ion-doped Pb(Mg 0.5 W 0.5 )O 3 -Pb(Zr, Ti)O 3 (PMW-PZT) ceramics. The study showed that the electrical properties of the ceramics were effectively improved.…”

KNN piezoelectric ceramics are of great importance in the field of scientific research due to their high Curie temperature, good electrical properties, etc. The application of potassium sodium niobate K0.5Na0.5NbO3 (KNN) is strictly limited due to the volatility of Na+ and K+ in KNN and its leakage current. In order to investigate the effect of Mn doping on KNN-based piezoelectric ceramic coatings, KNN and KNN-0.02Mn (KNMN) coatings were successfully prepared using a plasma spraying technique. The phase structure, microscopic morphology, and electrical properties of the coatings were studied in the research. The results showed that both the KNN and KNMN coatings had chalcogenide structures. The KNN coating had an orthogonal phase structure, whereas the KNMN coating had a tetragonal phase structure. Compared with the KNN coating, the microhardness of the KNMN coating was improved through doping with Mn ions. The doping of Mn ions could replace both the A and B sites in the KNN piezoelectric ceramics, further reducing the oxygen vacancies and leakage currents in the coating, and its dielectric properties were improved.

“…6 After the above analysis, the temperature insensitivity of hightemperature piezoelectric ceramics is the bottleneck in practical application. [7][8] Considerable efforts have been made to address temperature stability, such as phase structure regulation, MPB design, 7,9 elements replacement, 10 and ternary system construction. 11 Many reports have shown that the temperature stability of the ceramics systems with vertical phase boundaries is much better than that of the ceramic systems with other phase boundaries.…”

Phase structure has a strong influence on the temperature stability of ceramics; however, their influence on BiScO 3 -xPbTiO 3 has been neglected. To meet the requirements for practical applications, (0.98-x)BiScO 3 -xPbTiO 3 -0.02Bi(Sn 1/3 Nb 2/3 )O 3 (BS-xPT-BSN, 0.59 ≤ x ≤ 0.65) polycrystalline ferroelectrics with rhombohedral phase, morphotropic phase boundary (Cm and P4mm coexisting), and tetragonal phase has been prepared and studied. The relationship between the phase structures and temperature stability is established from the macro properties as well as the underlying domain behaviors. The results show that the tetragonal phase is not sensitive to temperature because of its stable domains, which is a positive motivator for improving the temperature stability of ceramics. This work provides a new strategy for the design of high-temperature piezoelectric ceramics in the future.

“…Piezoelectric materials containing lead zirconate titanate [Pb (Zr, Ti)O 3 ] have been widely applied in numerous fields because of their superior piezoelectric coefficients. [1][2][3][4] However, due to the lead oxide pollution in the environment, alternative lead-free piezoelectric materials with high performance are urgently needed. Consequently, exploration of high-performance lead-free piezoelectric materials has continued to increase in recent years.…”

“…7,9) Furthermore, thick films with the MPB composition (0.06 ⩽ x ⩽ 0.07) of (1 − x)(Bi 0.5 Na 0.5 )TiO 3 -xBaTiO 3 (BNT-xBT) show excellent properties and high T C . 4) However, due to the depolarization temperature (T d ) of BNT-xBT in the MPB, it is impossible to apply in a wide temperature range. 29,30) In previous studies, BNT-17BT, which has a higher T d than BNT-xBT with MPB compositions, was chosen and applied, and BNT-17BT thick films were prepared successfully on Al 2 O 3 substrates.…”

Lead-free piezoelectric 0.83(Bi0.5Na0.5)TiO3-0.17BaTiO3 (BNT-17BT) thick films were grown on MgO ceramic substrates via screen printing. Thick films with compressive stress formed a c-domain preferentially with a volume fraction of 0.88. High-temperature X-ray diffraction and piezoresponse force microscopy and the temperature dependence of the piezoelectric coefficient d33 data indicated that the thick films had a preferred c-domain during the transformation from the tetragonal phase to the cubic phase with temperature increasing. Based on polycrystalline MgO substrates with high thermal expansion coefficients, the thick films displayed a higher phase transition temperature and larger remanent polarization (Pr) values over 220 °C than those of thick films on Al2O3 substrates. The ferroelectric properties of BNT-17BT/MgO were better than those of soft PZT/YSZ and hard PZT/YSZ over 220 °C. The results showed the possibility of applying BNT-17BT thick films in a wide temperature range.
