Ba4HfCu
metal· JVASP-64244· Ba4HfCu
Ba4HfCu is an intermetallic compound combining barium, hafnium, and copper in a defined stoichiometry. This material belongs to the family of ternary and higher-order metallic systems and is primarily of research interest rather than established industrial production. The compound exemplifies materials exploration in high-entropy and complex metal systems, where unusual crystal structures and electronic properties may enable applications in advanced functional materials, such as thermoelectrics or specialized electronic components, though commercial deployment remains limited.
