摘要

Phase equilibria in the system BaAu-BaPt have been investigated by X-ray powder diffraction. Depending oil composition, three structure types occur, the FeB type for BaAu, and NiAs for BaPt, while the CrB type of structure is adopted in between, The homogeneity range for the CrB type of structure was established to extend from BaPt0.15Au0.85 to BaPt0.90Au0.10. The respective lattice parameters vary linearly, in accordance with Vegard's law. The crystal structure of the new CrB type compounds have been confirmed by X-ray powder diffraction for the solid solution range, and by single crystal X-ray diffraction exemplary for the composition BaAu0.5Pt0.5 (Cmem; a = 4.3915(5) angstrom; b = 11.9149(12) angstrom; c = 4.7920(5) angstrom; Z = 4). BaAu was also established by single crystal structure determination (Pnma: a = 8.3220(10) angstrom; b = 4.9252(10)angstrom ; c = 6.3844(10) angstrom; Z = 4) to complete the results. According to ESCA measurements BaAu0.5Pt0.5 and BaAu call be formulated as [Ba2+ . 0.5e(-)] center dot [Au-0.5(-) center dot Pt2- (0.5)] and [Ba2+ center dot e(-)] center dot [Au-]. respectively
