GERMANIUM(IV) FLUORIDE Chemical Properties,Usage,Production

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]
