Polycrystalline ceramics of bismuth layered structure of (Bi2O3)(BaxFe1-xO3) (0.2x0.8, x is in step of 0.2) have been prepared by conventional solid-state reaction method to study its modified dielectric and electrical properties. X-ray diffraction technique is used on the powdered samples for physical characterization and an average grain size of 16 – 21 nm was obtained. The XRD analysis rev...

A traditional composite cathode for proton-conducting solid oxide fuel cells (H-SOFCs) is typically obtained by mixing materials and proton conducting electrolyte of BaCe0.7Y0.2Zr0.1O3–? (BZCY), providing chemical thermal compatibility with the electrolyte. Here, a series triple-conducing cobalt-free iron-based perovskites as cathodes H-SOFCs reported. Specifically, BaCexFe1–xO3–? (x = 0.36, 0....

MgTi1−x(Mn1/3Nb2/3)xO3 (x = 0–0.30) ceramics were prepared via the solid-state reaction method. The phase composition, microstructure, bond characteristics, and microwave dielectric properties of systematically investigated. presented an ilmenite type with R-3 space group, secondary-phase MgTi2O5 only existed at x 0 0.30. introduction (Mn1/3Nb2/3)4+ effectively suppressed formation phase. varia...
