· JVASP-14906· CaAl2Si2

CaAl₂Si₂ is an intermetallic compound combining calcium, aluminum, and silicon—a lightweight ceramic-metallic material that bridges metallic and ceramic properties. This compound is primarily of research and developmental interest for aerospace and structural applications where weight reduction and thermal stability are critical; it represents the family of complex intermetallics being explored as alternatives to conventional aluminum alloys and titanium for high-temperature or weight-sensitive designs. The material's potential lies in its low density combined with moderate stiffness, making it a candidate for next-generation lightweight structural components, though industrial adoption remains limited compared to more mature alloy systems.
