SrMnO3 is a potential solid oxide fuel cell (SOFC) cathode material. However, the formation of different crystalline phases and poor sinterability restrict its application as in SOFC. Thus, present study focused on synthesis monophasic using sintering temperatures with variable durations. The X-ray diffraction confirms gradual transformation hexagonal to orthorhombic SrMnO3. Minor amounts Hausm...

Among various perovskite proton conducting oxides, Y-doped BaZrO3 is a promising material for electrochemical hydrogen devices due to the good chemical stability and higher conductivity at operating temperatures like 500-800 {\deg}C. For practical application of functional conductor in devices, its necessary understand isotopic effect conductivity. To barium zirconates, this study, Ar, (Ar + 4%...

The sintering is an essential step in the processing of ceramics materials. A number researchers have reported new techniques for sintering. However, general, process still demands high temperatures. This paper reports results cold ZnO-BaTiO3 composites. microstructural, structural, and electric properties composite were studied. We obtained densities (>95%) pure ZnO composition with 10 wt% BaT...
