· JVASP-37712· Na3Cr

Na3Cr is an intermetallic compound composed of sodium and chromium, belonging to the family of alkali-metal transition-metal intermetallics. This material exists primarily in research and experimental contexts rather than established industrial production, as it represents a niche composition within the broader field of lightweight metallic systems. The compound's potential applications center on advanced energy storage, high-temperature structural research, and exploratory studies in alkali-metal chemistry, where its unique phase behavior and low density make it a candidate for systems where weight reduction and novel electronic or thermal properties are scientifically interesting.
