Preparation, Sinterability, Electrical Transport and Thermal Expansion of Perovskite-Type La0.8Ca0.2CrO3 Composites

Preparation, Characterization, Thermal and Electrical Conductivity Properties of PVDF Composites

Using PVDF and ZrO2, polymer composites were prepared by sol gel method. Various measurements such as X-ray diffraction (XRD), Scanning electron microscopy (SEM) and Differential Scanning Calorimetry (DSC) were used to characterize the composites. Thermal and electrical properties of the composite samples were studied. The conductivity of composites was found to increase with increase in temper...

Preparation and Field-Induced Electrical Properties of Perovskite Relaxor Ferroelectrics

(111)-oriented and random oriented Pb0.8Ba0.2ZrO3 (PBZ) perovskite relaxor ferroelectric thin films were fabricated on Pt(111)/TiOx/SiO2/Si substrate by sol-gel method. Nano-scaled antiferroelectric and ferroelectric two-phase coexisted in both (111)-oriented and random oriented PBZ thin film. High dielectric tunability (i = 75%, E = 560 kV/ cm ) and figure-of-merit (FOM ~ 236) at room temperat...

Phase Transition and Thermal Expansion of MgSiO3 Perovskite.

Results from in situ x-ray diffraction experiments with a DIA-type cubic anvil apparatus (SAM 85) reveal that MgSiO(3) perovskite transforms from the orthorhombic Pbnm symmetry to another perovskite-type structure above 600 kelvin (K) at pressures of 7.3 gigapascals; the apparent volume increase across the transition is 0.7%. Unit-cell volume increased linearly with temperature, both below (1.4...
