Description

Hexachlorodisilane is a highly reactive inorganic compound primarily used as a crucial precursor in advanced materials synthesis. Its value lies in its ability to serve as a high-purity silicon source for depositing silicon-containing thin films. This chemical is essential for manufacturers and R&D facilities in the semiconductor and specialty chemicals industries, where it enables the production of silicon carbide, silicon nitride, and other high-performance ceramic materials.

Application

• Chemical Vapor Deposition (CVD) & Atomic Layer Deposition (ALD): A key silicon precursor for depositing silicon carbide (SiC) and silicon nitride (Si3N4) thin films on semiconductor wafers and optical components.
• Advanced Ceramics Manufacturing: Used in the synthesis of high-purity silicon-based ceramic powders and fibers for aerospace and automotive applications.
• Polymer & Silicone Chemistry: Serves as a reactive intermediate or cross-linking agent in the development of specialized silicone polymers and resins.
• Photovoltaics R&D: Investigated as a precursor material for next-generation thin-film solar cells and photovoltaic materials.
• Surface Modification: Employed to create silicon-rich functional coatings on various substrates to alter surface properties.
• Laboratory Synthesis: A valuable reagent in research laboratories for the preparation of novel organosilicon compounds and catalysts.

Quality Control

Our Hexachlorodisilane is produced and handled under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay by GC or titration and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and incompatible materials. Due to its highly volatile and hygroscopic nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) and handle in a controlled, moisture-free environment. Keep container tightly sealed when not in use.
