Germanium Oxide (GeO2) Powder

New product

Germanium dioxide is insoluble in water and hydrochloric acid and is soluble in alkali to produce germanate. A rutile-like structure is more soluble in water than hexagonal germanium dioxide and produces germanic acid when acting with water.

More info

HM provides high purity Germanium dioxide powder at a competitive price. Germanium dioxide is an inorganic compound with the formula GeO2 and is a germanium dioxide with the same electronic formula as carbon dioxide. For white powder or colorless crystallization, there is two hexagon system (low temperature stable) slightly soluble in water and insoluble program system, with a transition temperature of 1033℃. It is mainly used for making metal germanium and also for spectroscopic analysis and semiconductor material.

For making germanium, and also in the electronics industry. Use as a semiconductor material. It is used as a raw material for metal germanium and other Ge compounds, a catalyst for producing polyethylene terephthalate resin, and spectroscopic analysis and semiconductor materials. Optical glass phosphor can be manufactured, which can be used as a catalyst for oil refining, hydrogen, gasoline distillation, production of color film, and polyester fiber. Not only that, germanium dioxide is a polymerization catalyst, glass containing germanium dioxide has a high refractive index and dispersion performance, can be wide-angle camera and microscope lens, with the development of technology, germanium dioxide is widely used to make high pure metal germanium, germanium compounds, chemical catalyst and pharmaceutical industry, PET resin and electronic devices.

Packing & Shipping

Germanium dioxide powder should be stored in a ventilated and dry warehouse. The packaging shall be sealed and moisture-proof and do not contact with alkali and acids. Take it lightly when loading and unloading to prevent the glass bottle from breaking.
