Study on Pyrolysis Characteristics of Sulfr hexafluoride in a Trace-Oxygen

The ReaxFFSFO force field for a sf6 gas–O2 system is developed based on the density functional theory (DFT) calculation data. Then, a series of molecular dynamics (MD) simulations were performed. The results show that the main oxygen-containing compounds that appeared in the MD simulation include SOF4, SOF2, and SO2F2. The relative quantitative relationship between SOF2 and SOF4 can be used toGet price

Sulfur hexafluoride - Wikipedia

Like xenon, sulfur hexafluoride is a nontoxic gas, but by displacing oxygen in the lungs, it also carries the risk of asphyxia if too much is inhaled. Since it is more dense than air, a substantial quantity of gas, when released, will settle in low-lying areas and present a significant risk of asphyxiation if the area is entered.Get price
