As a salt that is poorly soluble in water, barium hexafluorosilicate precipitates from solutions that contain barium ions (e.g. barium chloride as well as hexafluorosilicate ions (e.g. hexafluorosilicic acid).[6]
The compound is used as a chemical reagent in experimental applications. In various chemical reactions and processes, the compound acts as a source of barium and hexafluorosilicate ions.[7]
It was also used as an insecticide.[8]
