Germanium OxideGermanium oxide materials consist of two varieties: germanium monoxide (GEO) and germanium dioxide (GEO2). Germanium monooxide is a dark, needle-shaped crystal that sublimates at 710°C. One crystal form of germanium dioxide is a white, hexagonal, tetragonal crystal. It has a melting points of 1086°C at 6.239g/cm3, but is not soluble in liquid water. Germanium monoxide easily becomes germanium dioxide by heating in air. Disproportionation reactions can occur easily when the material is heated alone. Germanium monooxide dissolves easily in acids and strong alkali solutions. This product is known for its reducing capabilities. Germanium dioxide remains stable under heating and in the air. Although it is not easily dissolvable in acid, germanium dioxide can dissolve well in alkali to create germanate. Germanium dioxide may be produced by burning the metal germanium, germanium sulfide or in the air or by oxidizing or dehydrating germanium with concentrated nitric. Germanium monooxide is made by heating germanium dioxide and hydrogen to make it.
Germanium OxidePreparation Germanium tetrachloridehydrolysis: Mix distilled water with germanium tetrachloride. Let stand overnight to produce germanium dioxide precipitation. After the time has expired, wash the lotion in cold water. Germanium oxide products can be obtained by drying at 200°C. Here is how to make germanium dioxide products: GeCl4 +2H2O=GeO2
