Abstract

Mechanochemical reaction between ammonium fluoride (NH₄F) and gallium fluoride trihydrate (GaF₃·3H₂O) at a ratio of 3:1 is conducted by grinding the mixture at room temperature using a planetrary ball mill. A single phase of ammonium hexafluorogallate ((NH₄)₃GaF₆) is obtained as a product of the reaction. Other alkali hexafluorogallates (K₃GaF₆, Na₃GaF₆, and Li₃GaF₆) also can be synthesized by grinding constituent components (AF and GaF₃·3H₂O) under proper grinding conditions. A reaction mechanism related to the dissolution of alkali fluorides in water is suggested.
