Mixed oxides of sodium, antimony (5+) and divalent metals (Ni, Co, Zn or Mg)
A family of α-NaFeO 2-type oxides Na xM (1+ x )/3Sb (2− x )/3O 2 ( M=Ni, Co, Zn, Mg; x≈0.8 or 0.9) has been prepared by solid state reactions and characterized by powder XRD. At x=1, ordering occurs with tripling the unit cells and formula units. The powder patterns for Na 3 M 2SbO 6 ( M=Ni, Co) com...
