Product Description

Product Descriptions:

Silane is a colorless gas that reacts with air, posing significant hazards. It can spontaneously ignite, producing dense white silica smoke. The intense heat from its combustion can cause severe, even fatal burns. If the flame reaches the cylinder valve, an explosion may occur. Rapid pressure release can also lead to explosive reactions. Non-combustive leaks are perilous, demanding immediate, cautious action. Personnel must be equipped with suitable protective gear to manage emergencies safely. Do not attempt to cut off the gas supply before the fire is completely extinguished.

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

Applications
Silane and its derivatives are pivotal in industrial and medical fields. As coupling agents, they enhance adhesion between glass or carbon fibers and polymer matrices, ensuring composite stability. Silane's versatility extends to forming bio-inert layers on titanium implants, creating water barriers, protecting masonry, and defending against graffiti. In semiconductor manufacturing, it applies polycrystalline silicon layers on wafers. In the 1990s, the semiconductor industry consumed approximately 300 metric tons annually. Currently, its use in low-cost solar photovoltaic module production is on the rise, particularly in depositing a-Si:H on various substrates. Despite a 15% utilization efficiency in PECVD processes, recycling efforts are underway to minimize waste and environmental impact.

In the realm of advanced propulsion systems, silane is utilized in supersonic combustion ramjets to ignite fuel. It burns with carbon dioxide as the oxidizer, making it a potential fuel for Mars-bound engines. This reaction, yielding solid byproducts like silicon dioxide and carbon, suits liquid-fuel rockets and 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.
