, doping level and doping sites at either A site or B site in ABO3 perovskite compounds on the magnetotransport properties of the compound has been extensively investigated[2-3]. However, low transition temperature, low room-temperature MR and high magnetic field are enormous challenges for many researchers. Recently, manganite-based composites have stimulated a surge of researching due to tunneling......
improved the photocatalytic activity of catalyst. Moreover, few reports are available on the photocatalytic reduction of Cr(VI) by perovskite photocatalysts[3, 9]. In this study, perovskite type SATBBFS... increases slightly with the increment of the calcination temperature. It can be observed from Fig.2 that the calcination temperature influences the perovskite content of SATBBFSx catalysts......

of Ti components by traditional separation methods. Based on the above characteristics of Ti components in the slag, a method, aiming to enrich the Ti components in blast furnace slag into perovskite phase, has been proposed and extensively studied [6]. Many studies [7-14] on enriching the Ti components in blast furnace slag into perovskite are available. However, it has been proved......
