1. Description
Disilane (Si2H6) is a colorless, highly flammable gas with a strong, unpleasant odor. It is chemically reactive and decomposes upon heating or exposure to air, forming silicon and hydrogen. Disilane is primarily used in the semiconductor industry for thin-film deposition processes, especially in low-pressure chemical vapor deposition (LPCVD) applications. It serves as a silicon source for the fabrication of microelectronic devices and photovoltaic materials.

| 1. What's your product price? Because each gas price depends on market supply and demand, quantity, and purity, it is difficult to give a fixed price. If If you have any interest in any gas, please give your details and requirements. We can negotiate the most reasonable price. 2. What's the minimum order quantity? Different products have different minimum order quantity. Please don't hesitate to let me know your requirement. 3. What's the delivery time? If the cylinder needs to be customized, the delivery is about 35 days ex-work after receiving the deposit. That depends on the quantity. 4. How do I check the gas quality? Firstly, our cylinder will take a treatment (cleaning, drying, vacuum pumping, and replacement) before filling gas. In this way, the cylinder inside is clear and dry. Secondly, we will take tests on every treated cylinder to assure their inside purity. Thirdly, We will take a test for all of the gas after filling the cylinders. If the tested gas is not up to standard, we will produce it again and not release the faulty product to ex work. At last, we will supply you the gas testing qualified report . |
