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...

A solid state synthesis of calcium manganite (CaMnO3) is described where equimolecular mixtures CaCO3:MnCO3 have been subjected to mechanical stress (high energy milling) so yielding CaCO3-MnCO3 solid solutions of nanometric particle size. TG measurements have shown that a link exists between milling time, the extent of non-stoichiometry and the milling-induced decomposition of MnCO3 to Mn3O4. ...
