Product Description

Product Descriptions:

Silane, a colorless gas, engages dynamically with air, releasing a powerful and dense smoke. Upon air exposure, silane ignites, producing a striking white amorphous silica smoke. The primary health hazard lies in its spontaneous combustion, posing risks of severe and potentially fatal burns. If flames or intense heat contact a part of the silane cylinder before the valve, an explosion might occur. Moreover, rapid or high-pressure discharge of silane may induce a delayed explosion. Any silane leak, if not ignited immediately, poses a serious threat and demands urgent attention. Emergency personnel must be equipped with specialized protective gear designed for fire safety. Never attempt to cut off the gas supply before ensuring complete flame extinction.

Silane gas is a colorless, toxic, and highly flammable substance, identifiable by an irritating garlic-like odor.

Application
Silane and its derivatives have a plethora of industrial and medical applications. They serve as coupling agents, effectively bonding glass or carbon fibers to polymer matrices, thereby enhancing the strength of composite materials. Silane coatings on glass fibers improve polymer adhesion. In medical applications, they enable bio-inert layers on titanium implants. Furthermore, silanes perform various roles like water repellents, masonry protection, and graffiti control. In semiconductor manufacturing, silane is essential for applying polycrystalline silicon layers on wafers. By the late 1990s, the semiconductor industry used approximately 300 metric tons of silane annually. The emergence of cost-effective solar photovoltaic module production has escalated silane's use for depositing hydrogenated amorphous silicon on substrates such as glass, metal, and plastic. Although the PECVD process is not material-efficient, wasting about 85% of silane, ongoing recycling initiatives aim to minimize waste and lessen the a-Si:H-based solar cells' ecological impact.

In advanced propulsion systems, silane is crucial for supersonic combustion ramjets, initiating combustion within the compressed air stream. Its capability to combust with carbon dioxide highlights its potential as a fuel for Mars-based engines. However, due to solid byproducts like silicon dioxide and carbon, it is best suited 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.
