Product Description

Product Descriptions:

Silane is a colorless gas that reacts dynamically with air, releasing an intense and thick smoke. Upon contact with air, silane ignites to produce a brilliant white amorphous silica smoke. The primary health hazard arises from its spontaneous combustion potential, posing a risk of severe and potentially life-threatening burns. In scenarios where flames or high heat impact a part of the silane cylinder before the valve, an explosion is a possibility. Moreover, rapid or high-pressure silane discharge can also lead to a delayed explosion. Any leak of silane gas, even without immediate combustion, represents a significant danger and demands urgent attention. Emergency personnel must don appropriate fire-resistant protective gear. It's crucial not to cut off the gas supply until the flames have been fully extinguished.

Silane gas, a colorless, toxic, and flammable substance, is characterized by a distinct and pungent garlic-like smell.

Application
Silane and its derivatives offer a multitude of industrial and medical applications. As coupling agents, they bind glass or carbon fibers to polymer matrices, thereby fortifying composite materials. Silane enhances polymer adhesion on glass fibers. In the medical realm, silanes create bio-inert layers on titanium implants. Additionally, they serve diverse roles, including acting as water repellents, masonry protection agents, and graffiti deterrents. In semiconductor manufacturing, silane is pivotal for the deposition of polycrystalline silicon layers on wafers. The late 1990s saw the semiconductor industry using approximately 300 metric tons of silane annually. The cost-effective production of solar photovoltaic modules has led to increased silane usage in depositing hydrogenated amorphous silicon on substrates like glass, metal, and plastic. Despite the PECVD process being material-inefficient-wasting about 85% of silane-recycling programs are underway to minimize waste and reduce the ecological impact of a-Si:H-based solar cells.

In cutting-edge propulsion systems, silane plays an essential role in supersonic combustion ramjets, initiating combustion within the compressed air stream. Its unique property of combusting with carbon dioxide makes it a viable candidate for Mars-based engines. However, the reaction produces solid byproducts like silicon dioxide and carbon, making it suitable only for liquid-fuel rockets utilizing liquid carbon dioxide, ramjets, or other advanced 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.
