Product Description

Product Descriptions:

Silane is an extraordinary colorless and highly reactive gas that bursts into a dazzling display of dense, white amorphous silica smoke when exposed to air, showcasing its unique nature. Despite its visual allure, it poses a significant health hazard, with the potential for severe, life-threatening burns. If flames or extreme heat reach the cylinder before the valve is cut off, it may lead to a catastrophic explosion. A rapid or high-pressure release can trigger an explosive event after a delay, posing major dangers. It's imperative to address any silane leak immediately, even without initial combustion, as it remains a grave threat. Emergency responders must be outfitted with specialized fire-retardant gear. Cutting off the gas supply should only be done once the fire is entirely controlled, ensuring safety.

Silane gas is a distinctively recognizable colorless, toxic, and highly flammable substance, marked by a unique, pungent garlic-like odor.

Application
Silane and its derivatives stand as vital contributors across numerous industrial and medical domains. They act as coupling agents, significantly enhancing the strength of composite materials by bonding glass or carbon fibers to polymer matrices. Furthermore, silane is instrumental in coating glass fibers to improve polymer adhesion. In the medical realm, it helps create bio-inert layers on titanium implants. Silanes also function as water repellents, guarding masonry, and assisting in graffiti control. In semiconductor fabrication, silane is essential for depositing polycrystalline silicon layers on wafers. By the late 1990s, the semiconductor sector consumed approximately 300 metric tons of silane annually. The rising production of affordable solar photovoltaic modules has further expanded silane's applications, particularly in depositing hydrogenated amorphous silicon on substrates like glass, metal, and plastic. Despite the PECVD process's inefficiency, which wastes about 85% of silane, continuous recycling efforts aim to minimize waste and mitigate the environmental impact of a-Si:H-based solar cells.

In advanced propulsion systems, silane plays a pivotal role, especially in supersonic combustion ramjets, where it aids in igniting fuel within compressed air streams. Its exceptional ability to combust with carbon dioxide makes it a promising candidate for fuels in Mars-based engines. However, the reaction generates solid byproducts like silicon dioxide and carbon, restricting its use to specialized applications such as liquid-fuel rockets using liquid CO2, ramjets, or 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.
