Product Description

Product Descriptions:

Silane is a colorless gas known for its reactive nature and potential hazards. Upon exposure to air, it ignites spontaneously, producing a dense, white cloud of amorphous silica smoke. This characteristic poses significant health risks, as the combustion flame can inflict severe thermal burns that may be fatal. If the valve of a silane cylinder is exposed to high temperatures, there's a risk of explosion. Furthermore, rapid or high-pressure discharge of silane can lead to delayed explosions. Even without spontaneous combustion, silane leaks are perilous and should not be ignored. Personnel handling emergencies must be equipped with appropriate protective gear designed for fire safety. It is crucial not to attempt cutting off the gas supply prior to extinguishing the flame.

Silane gas is a colorless, toxic, and flammable substance characterized by a pungent, garlic-like odor.

Application
Silane and its functionalized derivatives have numerous industrial and medical applications. They serve as coupling agents to bond fibers, such as glass and carbon, to polymer matrices, thereby reinforcing composite materials. This is achieved by silane's coating of glass fibers to improve adhesion to polymers. Additionally, silanes are employed to attach bio-inert layers on titanium implants. Other uses of silane include creating water repellents, protecting masonry, and controlling graffiti. In semiconductor manufacturing, silane is utilized to deposit polycrystalline silicon layers on wafers. The late 1990s saw the semiconductor industry consuming about 300 metric tons of silane annually. With the rise of low-cost solar photovoltaic modules, silane usage has surged, particularly for hydrogenated amorphous silicon (a-Si:H) deposition on substrates such as glass, metal, and plastic. However, the PECVD process is inefficient, wasting approximately 85% of the silane. Efforts to recycle and minimize waste and the ecological impact of a-Si:H-based solar cells are ongoing.

In the realm of supersonic combustion ramjets, silane is pivotal for initiating combustion in compressed air streams. Remarkably, it can combust using carbon dioxide as an oxidizer, making it a promising candidate fuel for engines on Mars. Due to its reaction yielding solid byproducts, including silicon dioxide and carbon, silane is best suited for liquid-fuel rockets, ramjets, and other 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.
