Er4 Cr4 B16
semiconductor· Er4 Cr4 B16
Er₄Cr₄B₁₆ is an erbium-chromium boride intermetallic compound belonging to the rare-earth transition metal boride family. This material is primarily of research and development interest for high-temperature applications where its ceramic-like hardness and potential thermal stability could provide advantages in extreme environments. Industrial adoption remains limited, with potential applications in specialized refractory coatings, wear-resistant surfaces, and high-temperature structural components where conventional alloys approach their thermal limits.
