Product Description

Product Descriptions:

Silane is an intriguing colorless gas that commands attention due to its highly reactive nature. Upon contact with air, it ignites spontaneously, creating a dense, strikingly white smoke composed of amorphous silica. This feature underlines the importance of handling silane with utmost caution, as it poses significant health risks, chiefly due to its potential to cause severe, even fatal burns. In the event of a flame or extreme heat reaching the cylinder before the valve, there's a risk of a catastrophic explosion. Additionally, silane discharged rapidly or at high pressure can result in a delayed explosion hazard. Unignited silane leaks are a critical safety concern and must be addressed immediately to prevent escalation. Emergency personnel must be equipped with comprehensive fire-resistant gear to ensure safety. It is imperative to never thwart the gas flow until the flames are fully extinguished.

Silane gas is a completely colorless, highly toxic, and markedly flammable substance, noted for its distinctively irritating garlic-like aroma.

Application
Silane and its versatile derivatives are indispensable in numerous industrial and medical arenas. As coupling agents, they excel in bonding glass or carbon fibers to polymer matrices, which significantly strengthens composite materials. These compounds also provide glass fibers with superior polymer adhesion. In the medical field, silane facilitates the formation of bio-inert layers on titanium implants, enhancing their performance. In addition, silanes fulfill a multitude of functions, such as acting as water repellents, protecting masonry, and controlling graffiti. In the semiconductor industry, silane is vital for depositing polycrystalline silicon layers on wafers. By the late 1990s, the semiconductor sector was consuming approximately 300 metric tons of silane annually. The surge in cost-effective solar photovoltaic module production has further amplified silane's application in depositing hydrogenated amorphous silicon on substrates like glass, metal, and plastic. Although the PECVD process is known for its material inefficiency, wasting around 85% of silane, ongoing recycling initiatives are making strides towards minimizing waste and reducing the ecological footprint associated with a-Si:H-based solar cells.

In cutting-edge propulsion systems, silane serves a pivotal role in supersonic combustion ramjets, where it initiates combustion within the compressed air stream. Its unique capacity to combust with carbon dioxide makes it a potential fuel source for engines based on Mars. However, the reaction produces solid byproducts, including silicon dioxide and carbon, which are only compatible with liquid-fuel rockets that use 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.
