CaCu5

CaCu5是一种金属间化合物，以六方晶系P6/mmm空间群结晶。G. Bruzzone (1971). The binary systems calcium-copper, strontium-copper and barium-copper. Journal of the Less-Common Metals, 25(4), 0–366. 它可由铜、氯化钙、氯化钠和钠的混合物（摩尔比5:1:1:4）经高温加热反应得到。Hiroshi Itahara, Naonari Sakamoto, Takeo Arai, Naoko Takahashi, Satoru Kosaka, and Yasuhiro Takatani.
