· JVASP-15839· Ca7Ge

Ca7Ge is an intermetallic ceramic compound composed of calcium and germanium, representing a research-phase material in the calcium-germanium system. This compound belongs to the broader family of intermetallic ceramics and rare-earth-free materials being explored for structural and functional applications where lightweight, stable compounds are needed. Ca7Ge is primarily of scientific and experimental interest rather than established in high-volume industrial production, with potential relevance to researchers developing advanced ceramics for thermal management, electronic substrates, or high-temperature applications where its thermal stability and lower density may offer advantages over conventional alternatives.
