  • DFT+U study of sulfur hexafluoride decomposition

    Oct 15, 2019Abstract. The detection of sulfur hexafluoride (SF 6) decomposition components is significant for monitoring the conditions of SF 6 -gas-insulated equipment. In present study, the adsorption of SF 6 and its decomposition components (H 2 S, SO 2, SOF 2, and SO 2 F 2) on ceria (110) was investigated by performing calculations based on density functional theory (DFT).

  • SF6 Gas Use in Electrical Applications - SF6

    Sep 03, 2018Sulphur hexafluoride (SF6) is a man-made gas comprising of one sulphur and six fluoride atoms. SF6 gas is extremely chemically stable, non-flammable and highly electronegative, with an excellent dielectric property of approximately 2.5 times more than air. Therefore, it is commonly used in electrical switchgear, transformers and substations as an electrical insulation, arc quenching and
