The importance of sulfur hexafluoride as insulating gas and arc quenching agent in high-voltage engineering has increased sharply in recent years. Knowledge of the decomposition products that occur during electrical loading is of practical interest because of their various properties, especially their corrosiveness and toxicity. After surveying a few important publication on this subject, we report on our own investigations of SF/sub 6/ decomposition in the 220 V ac arc and in the 12 kV spark, and on the products that are observed under those conditions. Decomposition mechanisms are discussed and then information is presented about the toxicity and corrosiveness of the SF/sub 6/ decomposition products.
