Germanium Sulfide

Germanium sulfide is white orthorhombic crystal, which is insoluble in strong acid, however it is soluble in ammonium hydroxide. When put it in aqua regia, it would resolve and dissolve in hot solution of  alkali metal hydroxide and ammonium hydroxide. Germanium sulfide would be oxidized when heating to 260~280℃. When it reacted with hydrogen peroxide, germanium dioxide is got. Germanium(II) sulfide is customizable. Germanium oxide act as raw material.
