“…Its solid solutions with PbTiO 3 , for example, are extensively used because they can preserve the high piezoelectric activity up to relatively high temperature and reduce the amount of lead. [1][2][3][4][5][6][7] First-principles calculations of piezoelectric alloys xBiScO 3 -͑1−x͒PbTiO 3 ͑Ref. 8͒ suggested that the large structural distortions and polarizations, at the morphotropic phase boundary, come from the hybridization between Bi/ Pb 6p and O 2p orbitals, a mechanism that is enhanced upon the substitution of Pb by Bi.…”

We systematically investigated the structure, electronic properties, zone-center phonon modes, and structure instability of four cubic perovskite BiMO 3 compounds, with three of the M ions being IIIB metals ͑Al, Ga, and In͒ and one IIIA transition-metal Sc, using first-principles density-functional calculations. Optimized lattice parameters, bulk moduli, band structures, densities of states, as well as charge density distributions are calculated and compared with the available theoretical data. Our results are in good agreement with those previously reported in the literature. All the BiMO 3 oxides considered in the present work are semiconductors with an indirect band gap between the occupied O 2p and unoccupied Bi 6p states varying between 0.17 and 1.57 eV. Their electronic properties are determined mainly by Bi-O bonding, which, in turn, depends on the M -O bonding. Ferroelectric properties of these oxides come from the 6s 2 lone pair on the A-site Bi ion and is similarly affected by the M ions through their influence on the Bi-O bonding, as suggested by our calculations of density of state, Born effective charge, and soft modes. The existence of soft modes and eight ͓111͔ minima suggests that the phase transition in BiAlO 3 has a mixed displacive and order-disorder character. There is evidence that ferroelectricity is absent in BiGaO 3 . Our investigation suggests that the BiMO 3 oxides or their modified versions are promising ferroelectric, piezoelectric, multiferroic, and photocatalytic materials.

“…The excellent performance of Bi-perovskites in solid solution with Pb-based perovskites were predicted and reported [2,3]. For example, PbTiO 3 -Bi(Zn 1/2 Ti 1/2 )O 3 [4][5][6], PbTiO 3 -Bi(Mg 1/2 Ti 1/2 )O 3 [7,8], PbTiO 3 -Bi(Ni 1/2 Ti 1/2 )O 3 [9], PbTiO 3 -BiScO 3 [10,11], and PbTiO 3 -BiInO 3 [12,13] compounds have been reported to exhibit a high Curie temperature (T C ), which is a great advantage for high temperature applications. These Biperovskites were also investigated in solid solutions with Pb-free ferroelectric materials such as BaTiO 3 .…”

Solid solutions xBaTiO 3 -(1-x)(0.5Bi(Zn 1/2 Ti 1/2 )O 3 -0.5BiInO 3 ), where x00.95-0.60, were prepared by conventional mixed oxide method. The single phase perovskite structure was obtained for the composition with x≥ 0.75. Phase transformation from tetragonal to pseudocubic was observed from x-ray diffraction patterns when x decreased from 0.95 to 0.75. In tetragonal phase region, x≥0.90, the increase of Bi(Zn 1/2 Ti 1/2 )O 3 -BiInO 3 content decreased the tetragonality and the temperature at which the relative permittivity is maximum (T max ). The increase in lattice parameter and T max were observed in the pseudocubic phase region, x< 0.90. Additionally, a highly broad and diffuse phase transition was observed from the dielectric data in the pseudocubic phase region. The introduction of Ba vacancies in compositions with x00.80 and 0.75 also improved dielectric loss at high temperatures. The incorporation of BiInO 3 into the BaTiO 3 -Bi(Zn 1/2 Ti 1/2 )O 3 compound was also found to improve the temperature coefficient of the relative permittivity, with values as low as approximately −1,000 ppm/K. Overall, ternary perovskite solid solutions based on adding Bi(Zn 1/2 Ti 1/2 )O 3 -BiInO 3 to BaTiO 3 shows excellent potential for high temperature capacitor applications Keywords High temperature capacitor .

Bi-perovskites, such as BiFeO3 (BF), BiInO3 (BI) and BiScO3 (BS), were added to (Li0.04K0.52Na0.44)(Nb0.84Ta0.1Sb0.06)O3 (LF4) to improve the piezoelectric properties of lead-free piezoelectric ceramics. The addition of Bi-perovskites up to 0.6 mol% did not depress the sinterbility of ceramics and the relative densities above 96% could be achieved by a powders-solid state reaction process. The c/a ratio of the tetragonal lattice of the LF4 ceramics was monotonously reduced with the amount of the BF added. The electrical insulation of the LF4 was improved with the addition BF, making the poling procedure under high electric fields become easy. The addition of BF was also effective to enhance the remnant polarization of the LF4 and the piezoelectric d33 constant of 358 pm/V was obtained by the addition of 0.4 mol% BiFeO3. However, the enhancement of the remnant polarization was not observed when the BI and BS were added to the LF4.
