Dielectric properties of Na1−xKxNbO3, near x = 0.5 morphotropic phase region

Annealing Temperature-Dependent Structural, Optical, and Electrical Properties of [(Ba1−zCaz)(Zr0.1Ti0.9)O3], (z = 0.155), Films

“…These lead-free perovskite solid solutions have attracted researchers due to their large dielectric-and piezo-constant, etc, and exceptionally extreme properties at specific compositions-near the morphotropic phase boundary (MPB). [22][23][24][25][26][27][28][29] Near the MPB, a composition-dependent transition and irregular variation in lattice parameters cause the extremal physical properties. [22][23][24][25][26][27][28][29] A MPB has been reportedly observed, at composition (Ba 1−z Ca z )(Zr 0.1 Ti 0.9 )O 3 , in the barium calcium zirconate titanate ((Ba,Ca)(Zr,Ti)O 3 ) system (BCZT system).…”

Composition Dependent Electrical Properties of (Ba1−xCaxZr0.1Ti0.9)O3 Ceramics, Near Morphotropic Phase Boundary (0.140 ≤ x ≤ 0.160)

“…An anomalous peak shifting in X-ray diffraction patterns have been reported close to the MPT (Morphotropic phase transition) region. 17 The dielectric and structural properties of Ba 1−x Ca x TiO 3 -BaZr y Ti 1−y O 3 (BCT-BZT) system have been explored by Tuan et al, near MPB. 18 Hanani et al 19 reported enhanced dielectric properties of (Ba 1−x Ca x Zr 0.1 Ti 0.9 )O 3 ceramics, at x = 0.150.…”

“…[23][24][25] The dielectric constant and electrical conductivity were reportedly found extremal, in the (Na,K)(Nb,Ta)O 3 system, near MPB. 17,26,27 The electrical properties of the perovskite materials significantly altered with the change in the preparation conditions and compositions of solid solution systems. In MPB, the separation of two different ferroelectric phases with different lattice parameters may result significant enhancement of electrical properties.…”

Biosynthesis of Metal Nanoparticles from Leaves of Ficus palmata and Evaluation of Their Anti-inflammatory and Anti-diabetic Activities

“…UV–vis data were recorded with an Electronics India (EI) double-beam spectrophotometer (model 3375). XRD data for the prepared powdered NP samples were recorded at room temperature with an X-ray diffractometer (PANalytical, X’PERT PRO), using Cu Kα1 radiation with a wavelength of 1.5405980 Å over a wide 2θ range (20° < 2θ < 70°) at a scanning rate of 6°/min . The surface morphology and grain size of the prepared Ag and ZnO NP samples were determined using SEM (CARL ZEISS, MA15/EVO18); TEM data were recorded at HV 120 kV, and TGA was performed with a model TGA-4000 instrument (Simultaneous TS).…”
