· MnF2

Manganese difluoride (MnF₂) is an ionic ceramic compound belonging to the metal fluoride family, characterized by a rutile crystal structure. It is primarily investigated in research contexts for battery electrode materials and as a precursor in fluoride-based ceramic synthesis, where its stability and fluoride content make it valuable for high-energy-density applications and solid-state electrolyte development.
