Investigation of isotopic composition of plasmachemical conversion products of sulfur hexafluoride

Abstract

The results of investigation of sulfur hexafluoride decomposition in mixture with hydrogen and oxygen in plasma of pulsed electron beam formed by accelerator TEA-500 (350...500 kV, 60 ns, current density 0,3...0,4 kA/cm2) have been presented. The data of thermodynamic simulation of gas mixture SF6+O2 and SF6+H2+O2 conversion in low-temperature plasma and gas mixture composition after electron beam influence measured by mass-spectrometer are given. It is shown that the formed gas-cycle compound synthesized in plasma of pulsed electron beam is sulfur difluoride-oxide. Isotope analysis of (SOF)+ and (SOF2)+ ions is carried out. It is obtained that sulfur isotope 34S content in sulfur difluoride-oxide exceeds its content in initial sulfur hexafluoride in 1,8±0,1 times
