Product Description

Product Descriptions:

Silane is a colorless gas that reacts with air and poses a significant choking hazard. Upon contact with air, it ignites, releasing a potent white silica smoke. The chief health risk stems from its spontaneous combustion, capable of causing severe thermal burns, which can be fatal. Exposure to flames or high temperatures near a silane cylinder may trigger an explosion. Rapid discharge can lead to delayed detonation. Even without spontaneous combustion, silane leaks are perilous. Personnel managing emergencies must use appropriate personal protective equipment for fire safety. Do not attempt to cut off the gas supply before extinguishing.

Silane gas is a colorless, toxic, and flammable substance with a distinctly pungent garlic-like odor.

Application
Silane and its derivatives are indispensable in numerous industrial and medical contexts. They act as coupling agents, bonding fibers like glass and carbon to polymer matrices, thus stabilizing composite materials. Silane enhances adhesion by coating glass fibers, and is vital in coupling bio-inert layers on titanium implants. Other roles include water repellency, masonry safeguarding, graffiti control, and as a sealant. In the semiconductor sector, silane was heavily consumed in the 1990s for polycrystalline silicon layer application on wafers. The rise of solar photovoltaics has spiked silane use for hydrogenated amorphous silicon deposition on diverse substrates. Despite inefficiencies, with 85% of silane wasted in PECVD processes, innovative recycling initiatives aim to reduce ecological impact and wastage in a-Si:H solar cells.

Silane finds usage in supersonic combustion ramjets, igniting combustion in compressed air streams. Its ability to combust with carbon dioxide as an oxidizer positions it as a potential fuel for Martian engines. Due to solid byproducts like silicon dioxide and carbon, it's ideal for liquid-fuel rockets, ramjets, and other 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.
