· JVASP-13023· HfTe4Cl6

HfTe4Cl6 is a ternary ceramic compound combining hafnium, tellurium, and chlorine—a research-phase material that belongs to the family of transition metal chalcohalides. While not yet commercialized, compounds in this family are investigated for their unique electronic and thermal properties, with potential applications in advanced ceramics and semiconductor research where hafnium's high-temperature stability and tellurium's chalcogen chemistry offer novel combinations not available in conventional materials.
