Systematic Investigations of the Solid Solution Zr(V_1-xAl_x)₂ Adopting the Laves Phase Structures.

ABSTRACT: Laves phases are an interesting field of research when it comes to structural chemistry and physical properties. Investigations of the ternary system Zr-V-Al showed, in contrast to the system Hf-V-Al, that no superstructures can be observed within the solid solution Zr(V_1-xAl_x)₂. High values of x form aluminum rich phases that adopt the hexagonal MgZn₂ type structure while low values of x lead to vanadium rich phases that adopt the cubic MgCu₂ type. All samples were investigated by powder X-ray diffraction experiments. Single crystal studies indicated that no superstructure formation is present in the investigated samples. ²⁷Al MAS NMR investigations confirmed these findings. For ZrAl₂, quantum-chemical calculatio
