text: # Lithium hexafluorogermanate
  
  Lithium hexafluorogermanate is the inorganic compound with the formula $Li_2GeF_6.$ It forms a solid off-white deliquescent powder. When exposed to moisture, it easily hydrolyses to release hydrogen fluoride and germanium tetrafluoride gases.
  
  ## Reactions and applications
  
  Lithium hexafluorogermanate can be dissolved in a solution of hydrogen fluoride, which forms a precipitate of lithium fluoride.
  
  It can be used as a densification aid in the sintering of gadolinium oxysulfide, and as a lithium salt additive in a lithium-ion battery electrolyte.
