· HfF4

Hafnium tetrafluoride (HfF₄) is an inorganic ceramic compound composed of hafnium and fluorine, belonging to the metal fluoride family of advanced ceramics. It is primarily of research and specialized industrial interest, valued for its high thermal stability, optical transparency in the infrared spectrum, and chemical resistance to aggressive environments. Applications span optical coatings for infrared systems, high-temperature crucible materials, and fluoride-based glass formulations; it is also investigated for nuclear fuel processing and specialized catalytic applications where hafnium's neutron-absorbing properties and fluorine's chemical reactivity are advantageous.
