Description

Germanium oxide (GeO2) is a white, amphoteric solid that occurs in two crystalline forms: hexagonal (hexagonal, rutile-like structure) and tetragonal (tetragonal, stishovite-like structure). The hexagonal form is the stable phase at room temperature, while the tetragonal form is stable at high pressures. Germanium dioxide can be synthesized by direct oxidation of germanium with oxygen at high temperatures. It is an important material in the electronics industry, used as a high-refractive index material in optical fibers and lenses. It is also used in the manufacture of solar cells and transistors. Germanium dioxide is also a catalyst for various organic reactions, including the oxidation of alcohols to aldehydes and ketones. In addition, germanium dioxide is a component of some alloys and ceramics.'

Research Excerpts

Toxicity

ExcerptReferenceRelevance
" Ge is widely distributed in edible foods, all of which, with few exceptions, contain less than 5 ppm Ge, since higher levels are toxic to most plants."( Nephrotoxicity and neurotoxicity in humans from organogermanium compounds and germanium dioxide.
Schauss, AG, 1991
)
0.28

Bioavailability

ExcerptReferenceRelevance
" When given orally, the apparent oxide bioavailability is very low (about 10%) but better than that of the sesquioxide."( [Absolute and relative bioavailability of germanium in the rabbit].

)

Dosage Studied

ExcerptRelevanceReference
" The distal tubular epithelium after 8 weeks dosage with the 1,500 ppm solution of GeO2 was characterized by vacuolization and deposits of PAS-positive material not only in adriamycin-treated rats, but also in normal rats."( Influence of propagermanium (SK-818) on chemically induced renal lesions in rats.
