Germanium concentrates can be treated via achlorine distillation method that produces germanium tetrachloride (GeCl4). This can then be hydrolyzed to GeO2. This form of germanium dioxide has ahexagonal crystal structure and is soluble in water at arate of 4.5g per litre (25°C)Applications:Germanium dioxide is used as acatalyst in the production of PET plastics used for heated beverage bottles, as well as as aprecursor to germane gas (GeH4), germanium tetrachloride (GeCl4) and zone refined germanium metal ingots. Used as raw material of metal germanium and other germanium, semi-conductor material and spectral analysis. It can be used to make Optical glass fluorescent powder, also can be used as catalyst, color film and polyester producing.Compound FormulaGeO2CAS1310-53-8Appearancewhite powder or colorless crystalsMolecular Weight104.6 g/molMelting Point:1,115° C(2,039° F)Density6.239 g/cm3Form Mcrystals or powderSolubility in water4.47 g/L (25 °C)10.7 g/L (100 °C)Solubilityinsoluble in HF, HClsoluble in other acid and alkaliImpurities in ppm GeO2 %99.999 minAs(ppm)0.5maxFe(ppm)1maxCu(ppm)0.2maxNi(ppm)0.2maxPb(ppm)0.1maxCo(ppm)0.2maxAl(ppm)1maxTotal content of impurity10maxThanks &Best RegardsGissing JiangWuhan Xinrong New Materials Co.,LtdWeb: www.91material.com
