Breakdown field strength of SF6, N2O, SF6+N2, and SF6+N2O

Journal of Applied Physics, 1981
The breakdown voltages of some electron attaching gases and gas mixtures have been calculated from their fundmental properties such as ionization and attachment cross sections, the momentum transfer cross section, the drift velocity or the mean energy of electrons.

Electrical breakdown of N2O, SF6 and N2O/SF6 mixtures

Proceedings of the Institution of Electrical Engineers, 1974
Measurements of static breakdown voltages were made for SF6 and N2O/SF6 mixtures containing between 1% and 50% SF6 by volume for values of Nds within the range 1023 < Nds < 1024 m−2 (where N is the gas number density and ds the sparking distance). These results, together with earlier data on N2O, show that the departures from Paschen's law become ...

SF6 ReUse Concept and SF6 New Applications

1998
Solvay is a worldwide supplier of SF6 since the late nineteen sixties and started to develop a ReUse concept for used SF6 at the begining of 1990. the ReUse concept was developed for SF6 coming from electrical equipment, where most of the worldwide SF6 production is used.

Transport of H2 and SF6 in the lung [PDF]

open access: possibleRespiration Physiology, 1975
The dead spaces for hydrogen and sulfur hexafluoride are predicted from the solution of a partial differential equation, applied to Weibel's morphometric data of the lung, and including longitudinal convection and diffusion coupled with instantaneous radial diffusion. Traces of H2 and SF6 were washed in and out of the lungs of two normal subjects. Dead

Muonic X-ray intensities in SF6 and in H2+SF6

Physics Letters A, 1973
Abstract With a high pressure gas target muonic F and S X-ray intensities in SF 6 and H 2 +SF 6 have been measured. It was found that the distribution of muons between sulphur and fluorine is not at all equal to the ratio of the atomic numbers Z .

Photodetachment of SF6−

Chemical Physics Letters, 1995
Abstract The photodetachment cross section for SF 6 − and the photodetachment threshold for this process have been accurately measured using a newly developed technique. The photodetachment cross section has a threshold at 3.16 eV which is about three times larger than the electron affinity of the SF 6 molecule.

Postpneumonectomy space control with SF6

The Japanese Journal of Surgery, 1991
Four cases of patients whose postpneumonectomy spaces had been controlled with SF6 were examined at autopsy, which showed that the spaces were entirely covered with thickening parietal pleura and that the mediastinum had moderate elasticity. Histologically, fibrotic changes with minimum inflammation patterns were seen in the pleura.
