Application

Germanium disulfide (GeS2) serves as a versatile material, primarily known for its semiconductor properties and applications in photo optics. This white crystalline solid, characterized as a 3-dimensional polymer, is notable for its high melting point. It can be synthesized through the reaction of hydrogen sulfide with germanium tetrachloride in concentrated hydrochloric acid. Additionally, germanium disulfide finds use in the creation of chalcogenide glasses, which are crucial for second harmonic generation processes in optical technologies.
