Ho2 B4 C4
semiconductor· Ho2 B4 C4
Ho₂B₄C₄ is a ternary ceramic compound combining holmium, boron, and carbon—a rare-earth borocarbide belonging to the broader family of transition-metal borocarbides. This is a research-phase material with limited commercial deployment; borocarbides are investigated for their potential hardness, thermal stability, and electronic properties, positioning them as candidates for extreme-environment applications where conventional ceramics or cermets may fall short.
