· JVASP-116990· Ca3Ge2Au9

Ca3Ge2Au9 is an intermetallic compound combining calcium, germanium, and gold in a defined crystalline structure. This is a research-phase material rather than an established industrial alloy; intermetallics of this type are investigated for specialized applications where unique electronic, thermal, or mechanical properties at high density are needed. The gold-containing composition places it in the family of precious-metal intermetallics, which are typically explored for applications demanding corrosion resistance, specific catalytic behavior, or unusual solid-state physics phenomena rather than for high-volume structural use.
