Germanium Oxide: What Does It Do?

Germaniumoxid, also known as white powder, is made up of hexagonal crystal systems, tetragonal and amorphous solids. It has a hexagonal morphology with a relative density 4.228. The melting point for this substance is 1115+-4 degC. Tetragonal germanium oxide morphology has a relative density (6.239) and a melt point (1086+-5). Germanium oxide does not dissolve in water, hydrochloric acid or alcohol. It can be dissolved in an alkaline solution to create germanate.

Germanium Oxide Classification

Germanium oxide materials consist of two varieties: germanium monoxide (GEO) and germanium dioxide (GEO2). Germanium monooxide is a black, needle-like crystal that sublimates to 710degC at which point it is insoluble. One crystal form of germanium dioxide is a white, tetragonal crystal that has a melting value of 1086C and a density at 6.239g/cm3. It is not soluble in liquid water. Another crystal form of germanium dioxide is a hexagonal white crystal which has a melting potential of 1115C and a boiling temperature of 1200degC. 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 Oxide Preparation

Germanium tetrachloridehydrolysis: Mix 6.5 times of distilled water with germanium tetrachloride. Let it 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

Germanium Oxide uses

Germanium oxide materials can be used for preparations of metal germanium, other germanium compounds and as catalysts to prepare polyethylene Terephthalate resins.
