ỨNG DỤNG
Scandium(III) fluoride, ScF3, is an ionic compound. It is slightly soluble in water but dissolves in the presence of excess fluoride to form ScF63−. ScF3can be produced by reacting scandium and fluorine. It is also formed during the extraction from the ore thortveitite by the reaction of Sc2O3with ammonium bifluoride at high temperature:
Sc2O3+ NH4HF2→ 2 ScF3+ 6 NH4F + 3 H2O
Additives can be prepared the metal scandium and improved alloys.
