Berkelium(III) fluoride

Berkelium(III) fluoride (BkF₃) is an inorganic chemical compound. It is a salt composed of berkelium in the +3 oxidation state and fluorine. As with other actinide trifluorides, it is an ionic compound. BkF₃ exists as a solid.

Berkelium(III) fluoride can be synthesized by reacting berkelium(III) oxide (Bk₂O₃) with hydrogen fluoride (HF) gas at elevated temperatures.

Due to the radioactivity of berkelium and the small quantities in which it is typically produced, BkF₃ is primarily studied in microscale quantities. It exhibits similar properties to other actinide trifluorides and is used in fundamental research related to actinide chemistry and materials science.
