Study on Pyrolysis Characteristics of sf 6 in a Trace-Oxygen

The ReaxFFSFO force field for a Sulfr hexafluoride–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
