Hydrothermal synthesis and characterization of double perovskite Ba2YSbO6

A mild hydrothermal process to prepare double perovskite Ba2YSbO6 is presented. The product was characterized on the basis of XRD, TEM, XPS, ICP and IR techniques. The product has a metal composition is close to double perovskite formula and a grain size range of 50–100 nm. The XRD patterns were refined by the Rietveld method by using the General Structure Analysis System (GSAS) refinement program. The product crystallizes in the cubic, space group Fm3m (no. 225), with a = 8.4117 (24) Å.
