Product Description

Product Descriptions:

Silane is an intriguing yet perilous colorless gas that reacts dramatically with the atmosphere, releasing a dense, choking smoke. When silane makes contact with air, it ignites spontaneously, producing a bright white haze of amorphous silica. The primary health hazard stems from its tendency for spontaneous combustion, which can lead to severe and potentially fatal burns. If the flame or intense heat reaches a section of the silane cylinder before the valve, an explosion could occur. Additionally, sudden or high-pressure discharge of silane can result in a delayed explosion. Any leak of silane without immediate combustion poses a significant risk and must be addressed without delay. Emergency personnel must wear specialized protective gear, designed specifically for fire safety. Never attempt to interrupt the gas supply until the flames have been fully extinguished.

Silane gas is a colorless, toxic, and highly flammable substance, characterized by its sharp, garlic-like odor.

Application
Silane and its derivatives boast far-reaching industrial and medical applications. They excel as coupling agents, enhancing the bonding of glass or carbon fibers to polymer matrices, thereby fortifying composite materials. Silane is integral in coating glass fibers to improve polymer adhesion. In medical fields, it facilitates the creation of bio-inert layers on titanium implants. Beyond this, silanes serve as water repellents, protect masonry, and manage graffiti control. In the semiconductor industry, silane is crucial for depositing polycrystalline silicon layers on wafers. By the late 1990s, the industry was consuming approximately 300 metric tons of silane annually. The affordability of solar photovoltaic modules has amplified silane's application in depositing hydrogenated amorphous silicon on substrates such as glass, metal, and plastic. Despite the material inefficiency of the PECVD process, which wastes about 85% of silane, ongoing recycling efforts aim to mitigate waste and minimize the environmental impact of a-Si:H-based solar cells.

In the world of advanced propulsion systems, silane is pivotal in supersonic combustion ramjets, where it initiates combustion within the compressed air stream. Its unique ability to combust with carbon dioxide positions it as a promising fuel for Mars-based engines. However, the reaction produces solid byproducts such as silicon dioxide and carbon, making it suitable primarily for liquid-fuel rockets that utilize liquid carbon dioxide, ramjets, or other sophisticated 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.
