GERMANIUM(IV) FLUORIDE Usage And Synthesis

Uses

Germanium tetrafluoride is used in the semiconductor industry for doping and ion implantation. Combined with silane gas, germanium tetrafluoride can be used to directly fabricate silicon-germanium microcrystals on glass substrates. Germanium tetrafluoride is also used as a synthesis agent in the chemical industry.

Chemical Properties

white crystal(s); deliquescent; obtained by slow evaporation of GeO2 in 20% HF [MER06] [CRC10]
