Product Name:Germanium(IV) sulfide
English Name:Germanium(IV) sulfide
CAS No.:12025-32-0
Aliases:Germanium disulfide, Germanium sulfide (GeS2)
Molecular Formula:GeS2
Physical Properties:White crystalline powder; density 2.19 g/cm³; melting point 800 °C; insoluble in water; soluble in alkali metal sulfide solutions or strong alkali solutions; slowly hydrolyzes in moist air.
Uses:Mainly used as a research material for infrared optical materials, chalcogenide glasses, and semiconductor thin films; also serves as a precursor for preparing high-purity germanium and other germanium compounds.
Technical Specifications:
Synthesis: prepared by vacuum melting 1 mol high-purity germanium with 2 mol high-purity sulfur under high temperature and pressure, followed by zone refining.
Purity: 5N (99.999%).
Impurity content: all impurity elements below 10 ppm determined by ICP-MS.
Phase purity: no GeS or other impurity phases detected by XRD.
Packaging: triple-layer vacuum packaging or argon gas protection.
