Product Description

Product Descriptions:

Silane is a colorless gas that exhibits a highly reactive nature when exposed to air, instantly generating a powerful and suffocating smoke. Upon air contact, silane ignites rapidly, creating a brilliant white cloud of amorphous silica. The primary hazard associated with silane is its spontaneous ignition, which can result in catastrophic burns. If the flame or extreme heat reaches the silane cylinder's body before the valve, it can lead to an explosion. Furthermore, a swift or high-pressure discharge of silane might instigate a subsequent explosion. Unignited silane leaks signify an acute danger and require immediate attention. Emergency responders must utilize appropriate protective gear designed for fire hazards. Never attempt to halt the gas supply until the fire is fully put out.

Silane gas is distinguished by its colorless appearance, toxic properties, flammable nature, and an irritant garlic-like odor.

Application
Silane and its derivatives serve a myriad of roles across industrial and medical sectors. For instance, they function as coupling agents, seamlessly bonding glass or carbon fibers to polymer matrices for stronger composite materials. Silane effectively coats glass fibers to enhance polymer adhesion. In medical contexts, they aid in creating bio-inert layers on titanium implants. Silanes also perform diverse functions such as water repellents, masonry preservation, and graffiti deterrence. Within semiconductor manufacturing, silane is indispensable for applying polycrystalline silicon layers on wafers. The semiconductor industry utilized approximately 300 metric tons of silane annually by the late 1990s. With the advent of cost-effective solar photovoltaic module production, the application of silane in depositing hydrogenated amorphous silicon on substrates like glass, metal, and plastic has surged. The PECVD process, known for its material inefficiency by wasting about 85% of silane, is seeing advancements in recycling efforts to mitigate waste and lessen the environmental impact of a-Si:H-based solar cells.

In the domain of cutting-edge propulsion systems, silane is pivotal for supersonic combustion ramjets, igniting combustion within compressed air streams. Its capacity to react with carbon dioxide marks it as a potential fuel for Mars-centric engines. However, the reaction results in solid byproducts such as silicon dioxide and carbon, making it suitable solely 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.
