Germanium disulfide refers to the chemical compound with the formula GeS2. It is a colourless white crystalline material, which melts at roughly 800 °C.[1][2]
Germanium sulfide was the first germanium compound found by Clemens Winkler during the analysis of argyrodite. The fact that germanium sulfide is not soluble in acidic water made it possible for Winkler to isolate the new element from the other elements.[3]
