Use
Germanium forms several tetravalent hydrides that have the general formula GenH2n+2 similar to alkanes and silicon hydrides. The formulas and CAS Registry numbers of the three common hydrides are: Name CAS No. Formula Monogermane (the tetrahydride) [7782-65-2] GeH4 Digermane [13818-89-8] Ge2H6 Trigermane [14691-44-2] Ge3H8 Monogermane is used to produce high purity germanium metal. It also is used as a doping substance for electronic components.
