The incorporation of low levels of sulfate/borate is sufficient to cause a change from a tetragonal to a cubic cell. Moreover, whereas heat treatment of undoped SrFeO3-δ under N2 leads to a transformation to brownmillerite Sr2Fe2O5 with oxygen vacancy ordering, the sulfate/borate-doped samples remain cubic under the same conditions. Thus, sulfate/borate doping appears to be successful in introducing oxide ion vacancy disorder in this system. 2017-06-06 completed University of Birmingham http://www.mdpi.com/journal/crystals 10.25500/eData.bham.00000026 Dataset research-data@contacts.bham.ac.uk School of Chemistry epsrc na na na TRUE Investigation into the Effect of Sulfate and Borate Incorporation on the Structure and Properties of SrFeO3-δ pub https://doi.org/10.3390/cryst7060169 IsSupplementTo
