2021-3-16SF6 can be heated without decomposition to 500&C in the absence of catalytic metals. SF6 is non-flammable and hydrogen, chlorine, and oxygen have no action on it. SF6 is insoluble in water and is not attacked by acids. Toxicity of arc products. Toxic decomposition products are formed when SF6 gas is subjected to

2018-9-29SF6 is a green-house gas with a high dangerous global worming po-tential (GWP) of 23900.The application of other gases with lower GWP is to be investigated. Three of such gases that might be of interest to replace SF6 in further applications are carbon-dioxide (CO2), dry air and nitrogen (N2).SF6 is expensive
