Packaging & Delivery
We provide versatile and highly secure packaging options to suit different consumption rates:
- Package Volume: Available in 38L cylinders for smaller scale operations and 200L drums for bulk industrial use.
- Fittings: All containers are equipped with precision 1/2" VCR and 1/4" VCR connections. These metal-gasket face seal fittings ensure absolute high-purity, leak-free transfer, critical for handling highly reactive TCS.
- Compliance: Fully certified for safe domestic and international chemical logistics.
Why Choose Us?
- Ultra-High Purity (99.99%): Our rigorous distillation ensures minimal carbon, boron, and phosphorus impurities, crucial for producing N-type and P-type semiconductor silicon.
- Premium VCR Technology: The use of VCR connections on our 38L and 200L packaging protects the liquid from atmospheric moisture, preventing hydrolysis and maintaining purity until the point of use.
- Stable Supply Chain: A 1,000 T/Y capacity guarantees that we can easily support the rapid scaling needs of the solar and electronics industries.
Applications
Trichlorosilane is the primary precursor in the silicon value chain:
- Polysilicon Production: The main raw material used in the Siemens process to produce ultra-pure polycrystalline silicon for solar panels and microchips.
- Silicon Epitaxy: Used for epitaxial silicon deposition on wafers in semiconductor device fabrication.
- Silane Coupling Agents: A vital chemical intermediate for manufacturing various specialized silane coupling agents.
