Product Description

Product Descriptions:

Silane, an intriguing yet perilous colorless gas, interacts dynamically with air to release a powerful and thick smoke. Upon contact with the atmosphere, it ignites spontaneously, creating a striking white amorphous silica smoke. The primary hazard associated with silane lies in its tendency to combust without warning, presenting significant risks of catastrophic burns. If flames or intense heat reach any section of the silane cylinder ahead of the control valve, an explosion might ensue. Furthermore, rapid or pressurized discharge of silane may lead to a delayed detonation. Any leak of silane not followed by immediate combustion should be regarded as extremely perilous and demands urgent attention. Personnel tasked with managing such emergencies must don protective equipment specifically designed for fire safety. It is critically important never to attempt to cut off the gas supply until the flames are completely quelled.

Silane gas is characterized by its colorless, toxic, and highly flammable nature, accompanied by an unmistakably pungent garlic-like odor.

Application
Silane and its various derivatives boast an array of industrial and medical applications. As coupling agents, they efficiently bond glass or carbon fibers to polymer matrices, reinforcing composite materials' strength. When utilized in coatings for glass fibers, they significantly enhance polymer adhesion. In medical spheres, silanes enable the formation of bio-inert layers on titanium implants. Beyond this, silanes serve multiple roles, including water repellents, protection for masonry, and graffiti deterrents. Within the semiconductor sector, silane is invaluable for layering polycrystalline silicon onto wafers. In the late 1990s, the semiconductor industry utilized approximately 300 metric tons of silane annually. The advent of cost-effective solar photovoltaic module production has further propelled its use, especially in depositing hydrogenated amorphous silicon on substrates such as glass, metal, and plastic. Despite the PECVD process's inefficiencies, wasting roughly 85% of silane, there are active recycling efforts to minimize waste and shrink the ecological impact of a-Si:H-based solar cells.

In cutting-edge propulsion technology, silane is pivotal for supersonic combustion ramjets, facilitating combustion within a compressed air stream. Its unique capability to react with carbon dioxide suggests its potential as fuel for Mars-bound engines. However, due to the resultant solid byproducts, such as silicon dioxide and carbon, it is most effectively suited for 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.
