Figure 9
Observed neutron diffraction pattern along with calculated and difference patterns from the Rietveld refinement of Ca2CrTaO6. The second set of reflection position markers are for the impurity phase Ca3(CaTa2)O9. The structure model for the impurity phase is based on the structure of Ca3(CaNb2)O9 (Levin, Chan, Geyer, Maslar & Vanderah, 2001). Vertical bars shown between the fit data and difference patterns indicate the 2θ position of the observed reflections. |
