1. Used for germanium, also used in the electronics industry. Used as semiconductor material. It is prepared by heating oxidation of germanium.
2. Used as raw material for the preparation of metallic germanium and other germanium compounds, as catalyst for the preparation of polyethylene terephthalate resin, as well as as spectroscopic analysis and semiconductor materials. It can produce optical glass phosphors and be used as catalyst for petroleum conversion, dehydrogenation and polyester fiber production.
3. Not only so, germanium dioxide or polymerization catalyst, glass containing germanium dioxide has high refractive index and dispersion performance, as a wide Angle lens camera and microscope, with the development of technology, germanium dioxide is widely used in the production of high purity metal germanium, germanium compounds, chemical catalysts and pharmaceutical industry, PET resin, electronic devices, etc.
