Figure 4
Diffraction patterns of CdSb, illustrating compound decomposition. (Left, upper panel) Ambient pressure: initial CdSb compound; (left, lower panel) P = 13 GPa: simple hexagonal phase and pure Cd (hcp) (λ = 0.3311 Å). (Right, lower panel) 30 GPa: further decomposition into nearly pure Cd (hcp) and SbII (host–guest) phases after annealing at ∼20 GPa and 423 K for 3 h; (right, upper panel) ambient pressure, on decompression: Cd (hcp) and SbI (λ = 0.3675 Å). Integrated spectra and Rietveld refinements are shown. |
