    SF6 (sulphur hexafluoride) is a non-combustible and non-toxic gas. Throughout the world it is used primarily for insulating electrical high-voltage switching systems, transformers and cables. It is also used as an etching gas in semiconductor production and as a tracer gas in environmental simulations.

  • Optical sensor for monitoring SF6 dissociation in high

    Aug 01, 2000Sulphur hexafluoride (SF 6 ) is used as an insulator in high voltage systems. Electrical breakdown in such a system dissociates SF 6 into sulphur fluorides, sulphur and fluorine. Some of these products react with contaminants such as water vapor and oxygen, and with metal surfaces and electrodes, to produce by-products including gaseous sulphur oxyfluorides, hydrogen fluoride andCited by: 4
