ThF4

Thorium tetrafluoride (ThF₄) is an inorganic ceramic compound composed of thorium and fluorine, belonging to the halide ceramic family. It is primarily investigated in nuclear fuel applications and advanced materials research, particularly for molten salt reactor (MSR) systems where it serves as a fluoride salt component, and in specialty optical or refractory applications. ThF₄ is notably more resistant to hydrolysis than some competing halide ceramics, making it valuable in high-temperature and chemically corrosive environments, though its use remains largely within research and specialized nuclear engineering contexts rather than mainstream industrial production.
