Decomposition of gaz sf6 and Production of S2F10 in Power Arcs

Abstract. Decomposition of SF 6 in electrical discharges produces many toxic solids and gases. S 2 F 10 is the most toxic of the gaseous byproducts and has been found in arcs, sparks and corona [1]. Of these, S 2 F 10 production in arcs is the least understood, in part because S 2 F 10 is known to decay rapidly at temperatures above 250°C [1].Get price
