· JVASP-34452· KTeHOF4

KTeHOF4 is a potassium tellurium hydrated oxide fluoride ceramic compound with a dense crystal structure, belonging to the family of mixed-anion ceramics that combine oxide and fluoride bonding networks. This material is primarily encountered in research and advanced materials development contexts, where it is investigated for applications requiring materials with specific optical, thermal, or structural properties that leverage the unique chemistry of tellurium-based oxide fluoride systems. The combination of potassium, tellurium, and fluorine creates a thermally and chemically distinct ceramic that may offer advantages in specialized niches such as optical coatings, solid-state laser hosts, or high-temperature structural applications where conventional oxides or fluorides fall short.
