Product Description

Product Descriptions:

Silane, a colorless gas, reacts with air to produce a potent choking hazard. When exposed to air, it ignites, releasing a dense white smoke of amorphous silica. The most pressing health risk is its spontaneous combustion, capable of causing severe thermal burns, which can be fatal. If a flame or extreme heat touches the silane cylinder before the valve is opened, an explosion is likely. Excessive discharge pressure or speed can lead to a delayed explosion. Uncontrolled leaks, if spontaneous combustion doesn't occur, pose a significant threat and must not be ignored. Personnel handling emergencies require customized protective gear, tailored fire safety measures, and should not attempt to cut off the gas supply before extinguishing the fire.

Silane is a colorless, toxic gas with a flammable nature and an irritating garlic-like odor.

Application
Silane and its functionalized derivatives boast a multitude of industrial and medical uses. Serving as coupling agents, silanes bond fibers like glass and carbon to polymer matrices, enhancing composite material stability. They also couple bio-inert layers on titanium implants. Additional applications include water repellents, masonry protection, graffiti control, depositing polycrystalline silicon layers on silicon wafers in semiconductor manufacturing, and creating sealants. In the late 1990s, the semiconductor industry consumed about 300 metric tons of silane annually. Recently, the burgeoning low-cost solar photovoltaic module manufacturing industry has significantly increased silane consumption, especially for hydrogenated amorphous silicon (a-Si:H) deposition on substrates such as glass, metal, and plastic. The PECVD process, although not resource-efficient with around 85% silane wastage, has sparked recycling initiatives to minimize ecological impact and material waste in a-Si:H solar cells.

Silane is pivotal for supersonic combustion ramjets, initiating combustion in compressed air streams. Capable of burning with carbon dioxide as an oxidizer, it is a promising candidate for Mars-based engine fuels. The reaction's byproducts, silicon dioxide and carbon, limit its application to liquid-fuel rockets using liquid carbon dioxide, ramjets, or other reactive 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.
