HfAs is a intermetallic ceramic compound combining hafnium and arsenic, representing a refractory material system with potential for high-temperature structural applications. This material belongs to the family of transition-metal pnictide ceramics, which are primarily explored in research contexts for their hardness, thermal stability, and wear resistance. HfAs and related compounds are of particular interest in aerospace and extreme-environment applications where conventional ceramics may degrade, though industrial adoption remains limited compared to established refractory systems like hafnium carbide or hafnium nitride.
