Hydrothermal Synthesis of a Novel Double Perovskite-type Oxide Ba(SbⅢ, SbⅤ )O3

Abstract

Abstract: A novel double perovskite-type oxide Ba(Sb ^Ⅲ, Sb^Ⅴ)O₃was synthesized by hydrothermal crystallization methods. The phase,
morphology and particle size of the product were characterized by XRD, IR, SEM and ICP techniques. The results indicated that the
Ba(Sb ^Ⅲ,Sb^Ⅴ)O₃oxide shows a cubic perovskite-type structure with a cell parameter a=0.415nm, and has a particle size in the range from 1 to 2μm.
The product has trivalent and pentavalent two states antimony ions. The influence of hydrothermal conditions exhibited that the optimum
alkalinity and n_{Sb( Ⅲ)}/n_Sb(Ⅴ) are 8～10 mol/L KOH medium and 0～1 respectively.

Key words: hydrothermal synthesis, perovskite, oxide, antimonate
