Product Description

Product Descriptions:

Silane is a colorless and highly reactive gas that dramatically ignites upon contact with air, creating a striking white amorphous silica smoke. This spontaneous combustion poses significant health hazards, with the potential for severe and life-threatening burns. If the flame or extreme heat reaches the silane cylinder's body before the valve, it could result in an explosion. Similarly, quick or high-pressure discharges might lead to delayed detonations. Any silane leak that doesn't immediately catch fire is extremely dangerous and requires urgent attention. Emergency responders should be equipped with specialized protective gear designed for fire safety, and it is crucial to never interrupt the gas supply before the fire is completely out.

Silane gas is recognized as a colorless, toxic, and flammable compound, known for its distinctive garlic-like odor that serves as a warning for its hazardous nature.

Application
Silane and its derivatives are integral to numerous industrial and medical applications. They serve as coupling agents, bonding elements like glass or carbon fibers to polymer matrices, enhancing the strength of composite materials. In the medical field, they contribute to bio-inert layer formation on titanium implants. Additionally, silanes are used in water repellents, masonry protection, and graffiti removal. In the semiconductor domain, silane is essential for depositing polycrystalline silicon layers on wafers. During the late 1990s, the semiconductor industry utilized 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 like glass, metal, and plastic. Though the PECVD process is known for its material inefficiency, wasting about 85% of silane, current recycling initiatives strive to mitigate waste and decrease the environmental impact of a-Si:H-based solar cells.

In modern propulsion systems, silane is pivotal for supersonic combustion ramjets, initiating combustion within the compressed air stream. This unique feature, coupled with its ability to combust with carbon dioxide, positions silane as a prospective fuel for Mars-based engines. However, the reaction byproducts, such as silicon dioxide and carbon, limit its use to 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.
