Al0.88Cu0.94Fe0.18

Abstract

The intermetallic phase with composition Al0.88Cu0.94Fe0.18 was synthesized by high-temperature sintering of a mixture with initial chemical composition Al78Cu48Fe13. Al0.88Cu0.94Fe0.18 adopts the CsCl structure type in space-group Pm\overline{3}m. The structure analysis revealed that one site is co-occupied by Al and Cu with a ratio of 0.88 (5):0.12 (5) and the other is co-occupied by Fe and Cu with a ratio of 0.2 (4):0.8 (4). The Al/Cu...Fe/Cu separation is 2.5465 (13) Å.
