· BiF3

Bismuth trifluoride (BiF₃) is an inorganic ionic ceramic compound composed of bismuth and fluorine, belonging to the rare-earth halide ceramic family. It is primarily investigated in research contexts for optical and electrochemical applications, particularly as a solid electrolyte material in advanced battery systems and as a component in specialized optical windows and photonic devices where its fluoride chemistry provides transparency in the infrared region. BiF₃ is notable for its potential in next-generation energy storage and solid-state ion conductor applications, though industrial deployment remains limited compared to more established ceramic electrolytes.
