Product Description

Product Descriptions:

Silane is a colorless gas that reacts with air, releasing a potent and choking smoke. When silane encounters air, it ignites, producing a vivid white amorphous silica smoke. The significant health risk comes from its spontaneous combustion, which can lead to severe, potentially fatal burns. Should the flame or intense heat reach a part of the silane cylinder before the valve, an explosion may occur. Additionally, rapid or high-pressure silane discharge can trigger a delayed explosion. Any silane leak without immediate combustion poses a grave threat and must not be ignored. Personnel managing emergencies must wear suitable protective gear tailored for fire safety. Never attempt to cut off the gas supply before the flames are completely extinguished.

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

Application
Silane and its derivatives find numerous industrial and medical applications. For instance, they act as coupling agents, bonding glass or carbon fibers to polymer matrices, thus strengthening composite materials. Silane coats glass fibers for enhanced polymer adhesion. In medical applications, they facilitate bio-inert layers on titanium implants. Moreover, silanes serve diverse roles such as water repellents, masonry protection, and graffiti control. In semiconductor manufacturing, silane is crucial for applying polycrystalline silicon layers on wafers. The late 1990s saw the semiconductor industry consuming around 300 metric tons of silane annually. The rise of affordable solar photovoltaic module production has increased silane's use in depositing hydrogenated amorphous silicon on substrates like glass, metal, and plastic. Though the PECVD process is material-inefficient, wasting approximately 85% of silane, ongoing recycling initiatives aim to curb waste and reduce the ecological footprint of a-Si:H-based solar cells.

In the realm of advanced propulsion systems, silane plays a critical role in supersonic combustion ramjets, initiating combustion within the compressed air stream. Its ability to combust with carbon dioxide positions it as a potential fuel for Mars-based engines. However, the reaction yields solid byproducts like silicon dioxide and carbon, so it is only fitting for liquid-fuel rockets that use 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.
