GeCl4

Germanium tetrachloride (GeCl4) is a volatile inorganic chloride compound that functions primarily as a precursor material rather than a final-form engineering ceramic. It is used extensively in optical fiber manufacturing and semiconductor processing, where it serves as a source material for depositing high-purity germanium oxide layers via chemical vapor deposition (CVD). The compound is valued for its ability to produce extremely pure and homogeneous coatings, making it essential in telecommunications infrastructure and integrated circuit fabrication where optical clarity and dopant precision are critical.
