Sodium hafnium fluoride (NaHfF₂) is an ionic ceramic compound combining hafnium—a refractory metal—with sodium and fluoride ligands. This material belongs to the family of metal fluorides, which are studied for applications requiring chemical stability, thermal resistance, and specific optical or thermal properties. While not widely commercialized in mainstream engineering, NaHfF₂ represents a research-phase ceramic of interest in specialized thermal, optical, and nuclear applications where hafnium-containing ceramics offer advantages in neutron absorption and extreme-temperature stability.
