Used in the production of semiconductor materials, particularly in the synthesis of high-purity germanium for electronics and infrared optics. Serves as a precursor in chemical vapor deposition (CVD) processes to create germanium-containing thin films for fiber-optic systems and solar cells. Also utilized in the manufacture of specialized glasses with high refractive index and low dispersion for lenses and optical instruments. Plays a role in research and development of advanced electronic devices due to its ability to dope silicon and enhance electrical properties.
