Material

Germanium dioxide

A refined germanium compound which the U.S. Geological Survey reports as consumed, with germanium tetrachloride, in the manufacture of fibre optic glass. The survey names the compound in words and publishes no formula for it here, so none is recorded.

Establishedgermanium dioxide and tetrachloride consumed in fibre optic glass manufacture

Reported for this deposit

A property of a dataset or model, shown here for context — not an observation about this record.

The U.S. Geological Survey reports fibre optics as the largest United States end use of germanium, and states that germanium dioxide and germanium tetrachloride are the forms consumed in manufacturing fibre optic glass for data networking and telecommunication. Its other named end uses — infrared optics, semiconductor and solar applications, radiation detectors — take germanium in different forms again.

  • assertion basis: SOURCE_REPORTED
  • generality: DATASET_PROPERTY
  • definition basis: End uses in descending order as the survey lists them, with the compounds it names for the first.
  • temporal basis: As reported for 2024.
  • assumption: End-use ordering is for the United States. This says nothing about quantities or about any producer.

Evidence support: Supported by the cited evidence one source
