Abstract

X-ray diffraction diagrams taken with Cu-K(alpha) radiation in a Bragg-Brentano diffractometer have shown that the La0.8Sr0.2CrO3 powders, synthesized by drip/spray pyrolysis in a rotating tube furnace at 600-700 oC, contained SrCrO4, in addition to the ceramic perovskite phase. By means of Rietveld powder profile multiphase refinements, the structure of the SrCrO4 compound was determined, crystallizing in the monoclinic space group P21/n (no. 14), with lattice parameters a = 6.73 Å, b = 7.33 Å, c = 7.07 Å, b = 104 degrees and Z = 4. The structure is similar to the structure of SrSeO4, as given in the literature.
