Used in the preparation of fluoride-containing materials for optical coatings and ceramics due to its stability and fluoride ion contribution. Serves as a reagent in chemical synthesis where controlled release of fluoride is required. Applied in some electroplating baths to modify deposit characteristics and improve corrosion resistance. Also investigated for use in solid-state batteries as a component in electrolyte materials because of zinc's electrochemical properties and the compound’s moderate ionic conductivity.
