Polycrystalline SrBi4Ti4O15 (SBiT) ceramics have been synthesized by a sol–gel method. These were structurally characterized powder x-ay diffraction studies (XRD), Rietveld analyses and scanning electron microscopy (SEM). The XRD pattern of SBiT crystallized into an orthorhombic structure with A21 am as space group. lattice parameters calculated refinement. SEM images show plate-like grains random orientation plate faces. Dielectric properties function temperature at different frequencies...
A substantial increase in sinterability, high‐temperature flexural strength, thermal stability combination with an average expansion of 0.42 × 10 −6 / ° C (30–1000°C) is achieved through magnesium silicate (Mg 3 Si 4 O (OH) 2 ) doping Aluminum Titanate (Al TiO 5 ceramics. Doped specimens exhibited the sintered density 99% theoretical at 1550°C and a maximum enhancement 169.23% (70 MPa) strength 1200°C as compared 26 MPa measured 30°C. Enhancement elevated temperature can be attributed to...
Abstract Solution cast and spin coating techniques were performed to deposit ferroelectric films of PVDF-PZT on Al 3+-ZnO/polyethylene terephthalate(PET) flexible substrates. The composites with 10wt% PZT in PVDF exhibited higher dielectric permittivity showed better property, might be due internal field generated by the nano particles, which favours orientation molecules. Higher remanent polarization low leakage current successfully demonstrated layer composite film. surface obtained smooth...
Investigations were carried out, on the effect of addition kaolinite (2Al 2 O 3 ·3SiO ·2H O) and talc (Mg Si 4 10 (OH) ) in terms bulk density, XRD phases, microstructure, as well thermal mechanical properties aluminium titanate (AT) ceramics. AT ceramics with additives have shown enhanced sinterability at 1550°C, achieving close to 99% TD (theoretical density) comparison 87% TD, exhibited pure samples sintered 1600°C, found be agreement microstructural observations. phase analysis maximum...
Polymer electrolytes consisting of poly(vinylidene fluoride-co-hexafluoropropylene) in combination with lithium triflate (LiCF 3 SO ) salt varying concentration have been prepared using the conventional solution casting technique argon atmosphere. Structural electrical characterizations synthesized performed various imaging and spectroscopic techniques. The DC conductivities determined by complex impedance plots reveal gradual increase up to a particular limit decrease subsequently. maximum...
Pure and Li-doped sodium ?-alumina (NaMg0.67Al10.33O17) ceramics were prepared from the stoichiometric mixture of raw powders. Pellets tubes formed precursor (NBA-1S) preformed powder through compaction extrusion processing, respectively. The obtained specimens finally sintered to dense ceramics. comparatively evaluated for their density, microstructure, phase formation electrical properties. Both pellets processed with (NBA-2S) showed enhanced densification along relatively better purity...
Aluminum titanate (Al2TiO5) green bodies were prepared from mixture of titania and alumina powders with different particle sizes by conventional slip casting (CSC), pressure (PSC) cold isostatic pressing (CIP). Precursor-powder mixtures evaluated respect to the powder properties, flow behaviours shaping parameters. Green densities measured correlated fractographs. A substantial increase in up 60 %TD (theoretical density 4.02 g/cm3, calculated based on rule mixtures) is observed application...
Wet-etching behavior of Lanthanum Strontium Manganate (LSMO) electrode and ferroelectric Pb 0.52 Zr 0.48 TiO 3 (PZT) for large area thin film using LSMO/PZT/LSMO micro-sensing device was investigated various etching solutions. The results show that PZT LSMO films can be protected by the Pt hard mask. mechanism attributed to double replacement reaction model. difference rates may cause damage upper electrodes resulting in failure. A careful design mask pattern a well control time are...
