Preparation Scheme and Application of Amorphous Solid Germanium Oxide

Germanium Oxide: What Does It Do?

Germanium oxide, also known as white powder, is made up of hexagonal, tetragonal, and amorphous crystals. The hexagonal morphology has a relative densitivity of 4.228 and its melting point is (1115+-4degC). The melting point for germanium oxide is (1086+-5degC). Germanium dioxide is not soluble in water or hydrochloric acids. However, it can dissolve in an alkaline solution to create germanate.

Germanium Oxide

Germanium oxide materials consist of two varieties: germanium monoxide (GEO) and germanium dioxide (GEO2). Germanium monooxide, also known as black-needle crystals, is sublimated 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 it’s 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.

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, rinse 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

Germanium dioxide substances are used for preparations of metal germanium, other germanium compounds and as catalysts to prepare polyethylene Terephthalate resins.
