Product Description

Product Descriptions:

Silane is a colorless gas, with a unique reaction profile when exposed to air, capable of emitting a white amorphous silica smoke upon combustion. Extreme caution is advised due to its potential health hazards, including choking and severe thermal burns. The spontaneous combustion of silane can be life-threatening, especially if ignited near the cylinder valve, leading to explosion risks. Rapid or high-pressure discharge may result in delayed explosions. In the absence of combustion, leaks remain highly dangerous and should never be disregarded. Emergency response personnel must be equipped with appropriate protective gear. It is crucial not to interrupt the gas flow until the fire is extinguished.

Silane gas is a colorless, toxic, and highly flammable substance, characterized by a distinct garlic-like odor that can be quite bothersome.

Application
Silane and its functionalized derivatives serve diverse industrial and medical purposes. Notably, they function as coupling agents, enabling the adhesion between fibers like glass or carbon and polymer matrices, thereby fortifying composite materials. Silanes are instrumental in coating glass fibers for enhanced polymer matrix bonding and are utilized for bio-inert layer coupling on titanium implants. Additional uses encompass water repellents, masonry protectors, graffiti control, and in semiconductor manufacturing, where they deposit polycrystalline silicon layers on wafers. The semiconductor sector's rising demand for cost-effective solar photovoltaic modules has spurred increased silane consumption, particularly for hydrogenated amorphous silicon deposition via PECVD-despite its low material efficiency, prompting recycling innovations to curtail waste and environmental impact.

Silane is also pivotal in supersonic combustion ramjets, facilitating combustion within compressed air streams. Its ability to combust with carbon dioxide as an oxidizer earmarks it as a potential propellant for Mars missions. However, due to the solid byproducts of the reaction, such as silicon dioxide and carbon, its use is restricted to liquid-fuel rockets, ramjets, and other specific 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.
