Product Description

Product Descriptions:

Silane is a colorless gas that reacts dramatically with air, emitting a potent and choking smoke. Upon contact with air, silane ignites spontaneously, creating a vivid white amorphous silica smoke. The primary health hazard arises from its tendency for sudden combustion, posing risks of severe, potentially life-threatening burns. If flames or intense heat reach any part of the silane cylinder before the valve, there is a serious risk of explosion. Rapid or high-pressure discharge of silane can also induce a delayed yet powerful explosion. Unattended silane leaks without immediate combustion are extremely hazardous and must be addressed at once. Emergency personnel must be equipped with specialized protective gear engineered for fire safety. Never attempt to cut off the gas supply until flames are fully extinguished.

Silane gas is a colorless, highly toxic, and flammable substance with an unmistakable odor reminiscent of garlic.

Application
Silane and its derivatives boast a multitude of industrial and medical applications. They serve as coupling agents, enhancing the bond between glass or carbon fibers and polymer matrices to fortify composite materials. Silane treatments on glass fibers significantly improve polymer adhesion. Medically, they are instrumental in creating bio-inert layers on titanium implants. Silanes also excel as water repellents, masonry protectors, and graffiti deterrents. In semiconductor fabrication, silane is indispensable for depositing polycrystalline silicon layers on wafers. By the late 1990s, about 300 metric tons of silane were used yearly in the semiconductor industry. The increased production of cost-effective solar photovoltaic modules has further elevated silane's role in applying hydrogenated amorphous silicon to substrates like glass, metal, and plastic. Although the PECVD process is known for low material efficiency, wasting around 85% of silane, ongoing recycling efforts aim to significantly reduce waste and the ecological impact of a-Si:H-based solar cells.

In advanced propulsion systems, silane is pivotal for supersonic combustion ramjets, initiating combustion within the compressed air stream. Its unique ability to react with carbon dioxide also positions it as a potential fuel choice for Mars-based engines, albeit with the formation of solid byproducts such as silicon dioxide and carbon, making it suitable primarily for liquid-fuel rockets using liquid carbon dioxide, ramjets, or other sophisticated reaction 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.
