Lithium hexafluorogermanate is the inorganic compound with the formula Li2GeF6. It forms a solid off-white deliquescent powder. When exposed to moisture, it easily hydrolyses to release hydrogen fluoride and germanium tetrafluoride gases.[1]
Reactions and applications
Lithium hexafluorogermanate can be dissolved in a solution of hydrogen fluoride, which forms a precipitate of lithium fluoride.[2]
It can be used as a densification aid in the sintering of gadolinium oxysulfide,[3][4] and as a lithium salt additive in a lithium-ion battery electrolyte.[5]
