Özet

Golden opportunity: Na₁₃Au₁₂Ga₁₅ is the first Na-containing, thermodynamically stable quasicrystal and was discovered during systematic exploration of the polar intermetallic Na-Au-Ga system. Its electron-to-atom ratio, 1.75, is extremely low for Bergman-type icosahedral phases, but it is the substantial Au content that allows Hume-Rothery stabilization and promotes novel Na-Au polar-covalent interactions, which stabilize the icosahedral phase.
