Germanium sulfide (GeS2) is a white powder with an orthorhombic crystal structure, known for its role as a minor metal sulfide. While it offers unique properties, GeS2 is relatively unstable, particularly at high temperatures, where it tends to sublimate and oxidize. In the presence of moisture or an inert atmosphere, germanium disulfide dissociates, when heated its molten state turns into a bright brown, transparent body, showcasing its complex thermodynamic behavior.

Germanium Sulfide

Chemical Properties:

• Solubility:Germanium disulfide is insoluble in water and inorganic acids, including even strong acids.However,it can dissolve in thermokalite,undergoing transformation into germanium amide.
• Oxidation:GeS2 begins to oxidize at temperatures between 260-280℃ in the presence of air.When oxidized by hydrogen peroxide, it forms germanium dioxide(GeO2).
• Volatility:Germanium disulfide is prone to sublimation and oxidation at elevated temperatures,making handling and storage conditions critical to maintaining stability.
