Lithium hexafluorogermanate is theinorganic compound with theformula Li2GeF6. It forms a solid off-whitedeliquescent powder. When exposed to moisture, it easily hydrolyses to releasehydrogen fluoride andgermanium tetrafluoride gases.[1]
Lithium hexafluorogermanate can be dissolved in a solution of hydrogen fluoride, which forms a precipitate oflithium fluoride.[2]
It can be used as a densification aid in the sintering ofgadolinium oxysulfide,[3][4] and as a lithium salt additive in a lithium-ion battery electrolyte.[5]
