· JVASP-36075· Na3Co

Na3Co is an intermetallic compound combining sodium and cobalt, representing an experimental material primarily of research interest rather than established industrial production. This compound belongs to the family of sodium-metal intermetallics, which are studied for potential applications in energy storage, lightweight structural composites, and advanced metallurgical systems where unconventional phase stability or electrochemical properties may offer advantages. While not yet widely deployed in commercial applications, materials in this compositional space are investigated as components in sodium-based batteries, thermal management systems, and as precursor phases in synthesis of specialty alloys.
