Product Description

Product Descriptions:

Silane, an intriguing colorless gas, instantly reacts with air, unleashing a robust and acrid smoke. When it meets air, it spontaneously combusts, producing a dramatic white amorphous silica smoke. The primary health hazard stems from its ability to ignite without warning, risking severe, possibly fatal burns. If flames or extreme heat reach any part of the silane cylinder before its valve, an explosion is a possible outcome. Furthermore, rapid or high-pressure silane releases can cause a delayed explosion. Any silane leakage that doesn't ignite immediately is extremely dangerous and demands urgent attention. Emergency personnel must wear specialized protective gear designed for fire safety. It's critical never to halt the gas supply until all flames are completely put out.

Silane gas is a colorless, toxic, highly flammable substance, distinguished by an irritating, garlic-like aroma.

Application
Silane and its derivatives boast a wide range of industrial and medical applications. They serve as coupling agents, effectively bonding glass or carbon fibers to polymer matrices, enhancing composite material strength. Silane also coats glass fibers to improve polymer adhesion. In medical domains, silanes aid in creating bio-inert layers on titanium implants. Additionally, silanes are employed as water repellents, protect masonry, and help control graffiti. In semiconductor production, silane is essential for applying polycrystalline silicon layers on wafers. By the late 1990s, the semiconductor industry utilized about 300 metric tons of silane each year. The increasing affordability of solar photovoltaic modules has amplified silane's role in depositing hydrogenated amorphous silicon on substrates such as glass, metal, and plastic. Although the PECVD process is not efficient with materials, wasting roughly 85% of silane, continuous recycling efforts are underway to minimize waste and lessen the environmental impact of a-Si:H-based solar cells.

Silane is pivotal in advanced propulsion systems, particularly in supersonic combustion ramjets, by initiating combustion within the compressed air stream. Its ability to react with carbon dioxide makes it a prospective fuel for engines on Mars. However, as the reaction produces solid byproducts like silicon dioxide and carbon, it's best suited for liquid-fuel rockets that utilize 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.
