Adsorption properties of Ag2O–MoSe2 towards SF6 decomposed products
Vacuum, 2021In this study, the adsorption and gas-sensing properties of Ag2O–MoSe2 to SF6 characteristic decomposition products (H2S, SO2, SOF2 and SO2F2), have been study based on the first-principle calculations.

An Effective Low-Contrast SF₆ Gas Leakage Detection Method for Infrared Imaging
IEEE Transactions on Instrumentation and Measurement, 2021Infrared noncontact detection has the advantages of having no power cut-off and convenient operation. However, when the SF6 (sulfur hexafluoride) gas leakage is small, the existing detection algorithms have low accuracy and are easily disturbed by noise.

Electrical breakdown of N2O, SF6 and N2O/SF6 mixtures
Proceedings of the Institution of Electrical Engineers, 1974Measurements 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
1998Solvay 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.
