High-Pressure Synthesis and Superconductivity of the Laves Phase Compound Ca(Al,Si)2 Composed of Truncated Tetrahedral Cages Ca@(Al,Si)12

The Zintl compound CaAl2Si2 peritectically decomposes to a new ternary cubic Laves phase Ca(Al,Si)2 and an Al–Si eutectic at temperatures above 750 °C under a pressure of 13 GPa. The ternary Laves phase compound can also be prepared as solid solutions Ca(Al1–x Si x )2 (0.35 ≤ x ≤ 0.75) directly from...
