Description

Germanium(IV) Chloride is a highly volatile, inorganic compound that serves as a critical precursor in advanced material synthesis. Its primary value lies in its role as a high-purity source of germanium for the production of semiconductors and specialty optical glasses. This material is essential for manufacturers and R&D facilities in the electronics, fiber optics, and infrared optics industries seeking reliable, high-grade inorganic intermediates.

Application

• Semiconductor Manufacturing: Key precursor for chemical vapor deposition (CVD) of germanium and germanium-silicon (Ge-Si) films in microelectronics.
• Optical Fiber Production: Used in the synthesis of germanium-doped silica glass for the core of optical fibers, enhancing the refractive index.
• Infrared Optics: Serves as a starting material for producing germanium dioxide and metallic germanium used in infrared lenses and windows.
• Catalysis Research: Employed as a Lewis acid catalyst in specialized organic synthesis and polymerization reactions.
• Thin-Film Coatings: Utilized in plasma-enhanced CVD (PECVD) processes to deposit germanium-containing coatings for solar cells and sensors.
• Chemical Synthesis: Intermediate for the preparation of organogermanium compounds and other germanium derivatives.

Quality Control

Our Germanium(IV) Chloride is produced under stringent conditions to meet the high-purity demands of advanced material applications. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling by ICP-MS, and physical property verification. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to ensure traceability and compliance with your quality protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and active metals. Due to its highly volatile and moisture-sensitive nature, containers should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use. Recommended storage temperature is 15-25°C.
