“…There were three possible situations. First, when Sb 3+ entered the A-site, there would be excess positive charge in the lattice as shown in defect reaction (3). Due to the imbalance of charge valence, Pb vacancy would be generated.…”

“…From the perspective of application, the doping is mainly divided into soft and hard doping. The soft doping can improve the piezoelectric coefficient of PZT ceramics (d 33 can reach 500-800 pC/N), and the main doping elements include A-doped Ba 2+ , Sr 2+ , 3 and lanthanide rare-earth elements and B-doped Nb 5+ and Ta 5+ . [4][5][6] Mirzaei et al prepared Nb 5+ doping PZT ceramics, which had enhanced dielectric properties (ε r ∼ 17960) and reduced T C in comparison with undoped PZT.…”

Lead zirconate titanate (PZT)–based piezoelectric ceramics as important functional materials are widely used in many electromechanical devices. The piezoelectric coefficient and mechanical quality factor are vital property parameters for piezoelectric applications. However, the piezoelectric coefficient is inversely proportional to the mechanical quality factor, resulting in a strong limitation among wide applications. Herein, piezoelectric ceramics composed of (xSb2O3, 0.3‐wt% MnCO3)‐doped (Pb0.92Sr0.08)(Zr0.533Ti0.443Nb0.024)O3 ((xSb, Mn)‐PSZTN) were prepared by a conventional solid‐state process. The excellent piezoelectric properties d33 = 554 pC/N, kp = 0.645, and high mechanical quality factor Qm = 540 were simultaneously obtained at x = 0.1 ceramic in the morphotropic phase boundary region. The enhancement of piezoelectric properties was mainly due to the contribution of irreversible domain wall motion. In particular, the regulation of different defect chemical reactions on the properties showed that Sb2O3 could play the role of both donor and acceptor dopant. This work demonstrated that (0.1Sb, Mn)‐PSZTN ceramic was a good candidate material for high‐power piezoelectric devices.

“…Recently, significant progress has been made in developing lead-free BT-based ceramics with remarkable electrical properties. This advancement is primarily attributed to the advantageous impact of Sr-doping on enhancing the dielectric properties of BST-based ceramics [5][6][7][8][9][10][11][12]. However, it is worth noting that excessive strontium incorporation not only compromises the piezoelectric characteristics but also leads to a substantial reduction in the Curie temperature (TC), which is evidenced by a distinctive single peak observed within the low room-temperature range of the dielectric temperature curve [7,[9][10].…”

Excessive Sr-doping has been observed to lead to a deterioration in the piezoelectric properties of BT-based ceramics. In response to this issue, this study introduces a solution through the development of lead-free piezoceramics using the composition (1-2x)Ba0.86Sr0.14Ti0.90Sn0.10O3-2xBa0.86Ca0.14Ti0.90Sn0.10O3 (BSTS-xBCTS), prepared through the conventional solid-state method. The rhombohedral, orthorhombic, and tetragonal phase coexistence is determined in the ceramic with 0.2≤x≤0.04. with x=0.3, the BSTS-xBCTS ceramic shows a sizeable piezoelectric property (d 33∼ 540 pC/N) and high ε r value (∼ 10280), superior or comparable to the other BT-based or lead-based ceramics. These results demonstrate that the electrical property of the BSTS-xBCTS ceramic exceeds those of some lead-based ceramics or equivalent and holds significant potential in various technological applications that require electrical materials.

“…However, high dielectric permittivity of pure ferroelectric BST ceramic also limit its application in microwave devices which require low dielectric constant with low dielectric loss [8]. The various properties can be modi ed by substituting various selected ions on either A site or B site [9,10]. The high tangent loss and permittivity of BST have hindered its application [11].…”

Barium Strontium Titanate exhibits ferroelectric or paraelectric behaviour that depends upon the composition and other factors, making it suitable for a number of applications. We have adopted conventional solid state reaction route to synthesize magnesium substituted barium strontium titanate with low concentration of Mg (Mg= 0.005, 0.010 and 0.015). X-ray diffraction has con rmed the perovskite cubic single phase. The dielectric studies were carried out as a function of temperature at different xed frequencies (1kHz, 10kHz, 50kHz and 100kHz) and as a function of frequency at room temperature. The Curie's temperature of pure BST was 96°C and for Mg substituted BST samples it dropped from 85°C to 63°C. The dielectric permittivity rstly suppressed and then maximum value observed for Mg content 0.015 and dielectric loss is also less than one. The remanance (P r ) and coercivity (E c ) are obtained and analysed for ceramics samples. Improvement in dielectric properties due to substitution of Magnesium is observed.
