Product Description

Product Descriptions:

Silane is a colorless gas that reacts with air, releasing a potent and choking smoke. This reactive gas boasts spontaneous ignition when exposed to air, creating a vivid white amorphous silica smoke. A significant health risk associated with silane is its tendency for spontaneous combustion, which can lead to severe and potentially life-threatening burns. If flames or intense heat reaches any part of the silane cylinder before the valve, an explosion may ensue. Additionally, rapid or high-pressure silane discharge can trigger a delayed explosion. Silane leaks that do not combust immediately are extremely hazardous and should never be ignored. Personnel handling emergencies must wear suitable protective gear designed for fire safety. Never attempt to interrupt the gas supply before the flames are completely extinguished.

Silane gas is a colorless, toxic, and highly flammable vapor with a distinctly irritating garlic-like odor.

Application
Silane and its derivatives are indispensable across a myriad of industrial and medical applications. They act as coupling agents to bond glass or carbon fibers to polymer matrices, thereby enhancing the strength of composite materials. Silane is used to coat glass fibers to improve polymer adhesion. In the medical field, silanes are instrumental in forming bio-inert layers on titanium implants. They also function as water repellents, provide masonry protection, and assist in graffiti control. In the semiconductor sector, silane is critical for applying polycrystalline silicon layers on wafers. By the late 1990s, the semiconductor industry consumed approximately 300 metric tons of silane annually. Affordable solar photovoltaic module production has surged silane's usage in depositing hydrogenated amorphous silicon onto substrates like glass, metal, and plastic. Despite the material-inefficient PECVD process, which wastes about 85% of silane, ongoing recycling efforts aim to reduce waste and lessen the ecological impact of a-Si:H-based solar cells.

Within the advanced propulsion system domain, silane is integral to supersonic combustion ramjets, where it initiates combustion in compressed air streams. Its capability to combust with carbon dioxide makes it a prospective fuel for Mars-based engines. Nevertheless, the reaction yields solid byproducts such as silicon dioxide and carbon, thus it is only suitable for liquid-fuel rockets utilizing liquid carbon dioxide, ramjets, or other sophisticated reactive 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.
