Figure 10
Calculated and observed X-ray diffraction pattern of the Rietveld refinement for LiCuSbO4. The difference curve is shown in blue; reflection positions are indicated by the vertical lines for LiCuSbO4 (blue), LiSbO3 [2.36(5) wt%] (red) and CuO [0.72(1) wt%] (green) impurity phases. (\(\lambda =0.70932\,{\AA }\), Bragg R-factor: 3.38%; Rf-factor = 3.49%; Bragg R-factor = \(\sum |{I}_{{\rm{ko}}}-{I}_{{\rm{kc}}}|/\sum {I}_{{\rm{ko}}}\); Rf-factor = \({[(N-P)/\sum {w}_{{\rm{i}}}{y}_{{\rm{io}}}2]}^{\mathrm{1/2}}\)). The inset shows optical image of a typical green pellet of polycrystalline sample of LiCuSbO4 after annealing in dried oxygen flow.
