Product Description

Product Descriptions:

Silane is an invisible yet highly reactive gas, unleashing a powerful, suffocating smoke upon contact with air. This spontaneous reaction ignites silane, producing a striking white, amorphous silica smoke. Its inherent risks lie in its volatile combustion, capable of causing severe, life-threatening burns. If flames or intense heat breach a silane cylinder before the valve, an explosion could ensue. Furthermore, swift or pressurized silane releases might spark a delayed detonation. Any silane leak not instantly combusted poses a severe hazard and demands immediate attention. Emergency personnel must be equipped with proper fire safety gear, and the gas supply should only be halted once flames are fully subdued.

Silane gas, characterized by its colorless, toxic, and flammable nature, exudes a distinct, pungent garlic-like aroma.

Application
Silane and its derivatives boast extensive industrial and medical applications. As coupling agents, they bond glass or carbon fibers to polymer matrices, reinforcing composite materials. Silane-treated glass fibers exhibit superior polymer adhesion. In medical fields, they enable bio-inert coatings on titanium implants. Silanes also function as water repellents, masonry protectors, and graffiti deterrents. Within semiconductor fabrication, silane is integral to depositing polycrystalline silicon layers on wafers. During the late 1990s, the semiconductor sphere utilized roughly 300 metric tons of silane annually. The surge in cost-effective solar photovoltaic module manufacturing has elevated silane's role in applying hydrogenated amorphous silicon on substrates like glass, metal, and plastic. Although the PECVD method is inefficient, wasting about 85% of silane, recycling initiatives strive to minimize waste and lessen the ecological impact of a-Si:H-based solar cells.

Silane is pivotal in advanced propulsion systems, particularly in supersonic combustion ramjets, igniting combustion within high-speed air streams. Its capacity to combust with carbon dioxide renders it a viable fuel option for Mars-based engines. However, the reaction results in solid byproducts such as silicon dioxide and carbon, making it suitable only for liquid-fuel rockets utilizing liquid carbon dioxide, ramjets, or other sophisticated reactive engines.

FAQ

Q: What's your product price?
A: Pricing for each gas is influenced by market supply and demand, quantity, and purity, making it difficult to set a fixed price. If you are interested in any specific gas, please provide your detailed requirements, and I would be happy to offer you a tailored quote.
Q: What is the minimum order quantity?
A: Minimum order quantities vary across different products. Please share your specific requirements with us, and we will provide the relevant details.
Q: What is the delivery time?
A: If the cylinder is in stock and only requires gas filling, delivery is approximately 7-10 days ex-works after receiving the deposit. Custom cylinder orders require about 15-35 days ex-works post-deposit, depending on the quantity.
Q: How do you ensure gas quality?
A: Our cylinders undergo a thorough treatment process, including cleaning, drying, vacuum pumping, and replacement before gas filling to ensure they are clear and dry. Each treated cylinder is tested for internal purity. After filling, all gases are tested once more. If the gas fails to meet standards, it is reprocessed. Finally, we provide a qualified gas test report.
Q: Are all cylinders recyclable?
A: Typically, seamless steel cylinders are recyclable. However, disposable cylinders are intended for single use only.
Q: Can we send back cylinders to China for refilling?
A: Yes, you can send back our cylinders for refilling. Inform us before exporting, and we will manage all necessary import customs clearance formalities.
