Introduction to Our Product Line

Detailed Product Insights:

Silane, a colorless gas, presents a notable hazard due to its reactive nature with air, where it forms a thick, choking smoke upon ignition. This spontaneous combustion produces vivid white amorphous silica smoke and poses substantial health risks, including severe burns. A critical concern is the potential for explosion if flames penetrate the silane cylinder before reaching the valve. High-pressure or rapid discharge of silane can trigger delayed explosions. Any leaks must be taken seriously: even those without immediate combustion are dangerous and warrant immediate action. It is crucial that emergency handlers don protective gear designed for fire safety. Never attempt to terminate the gas supply until all flames are fully extinguished.

Silane gas is a colorless, highly toxic, and flammable substance with a distinctive and pungent garlic-like aroma.

Applications and Uses
Silane and its derivatives boast widespread industrial and medical applications. They function as coupling agents, enhancing the bond between glass or carbon fibers and polymer matrices to fortify composite materials. Silane's application extends to glass fiber coatings, augmenting polymer adhesion. Medically, it is integral in forming bio-inert layers on titanium implants. In addition, silanes perform various roles such as water repellents, masonry protection, and graffiti deterrence. In semiconductor manufacturing, silane is essential for depositing polycrystalline silicon layers on wafers. The late 1990s saw the semiconductor industry's demand reaching approximately 300 metric tons yearly. The burgeoning production of cost-effective solar photovoltaic modules has spurred silane's use in depositing hydrogenated amorphous silicon on substrates including glass, metal, and plastic. Although the PECVD process proves material-inefficient, squandering nearly 85% of silane, persistent recycling efforts are underway to mitigate waste and lessen the environmental impact of a-Si:H-based solar cells.

In the cutting-edge domain of advanced propulsion systems, silane is invaluable to supersonic combustion ramjets, initiating combustion in compressed air streams. Its capacity to ignite with carbon dioxide presents it as a viable fuel for Mars-based engines. However, the reaction yields solid byproducts such as silicon dioxide and carbon, making it suitable for only certain rocket types, like 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.
