  • New SI-traceable reference gas mixtures for sulfur

    We developed two SI-traceable methods, using both static and dynamic preparation steps, to produce reference gas mixtures for sulfur hexafluoride (SF6) in gas cylinders at pmol/mol level. This research activity is conducted under the framework of the European EMRP HIGHGAS project, in support of the high quality measurements of this important greenhouse gas in the earths atmosphere.

  • 15 FAQs about SF6 Gas and SF6 Breakers - WIKA blog

    Sulfur hexafluoride (SF 6) has extremely good electrical and thermal insulation properties. For that reason, it is widely used in médium-and high-voltage electrical power transmission and distribution (TD). But it requires careful handling. Here are 15 FAQs about this gas, its chemical properties, and how to use it safely and efficiently.

  • Silicon etch using SF6/C4F8/Ar gas mixtures: Journal of

    May 30, 2014While plasmas using mixtures of SF 6, C 4 F 8, and Ar are widely used in deep silicon etching, very few studies have linked the discharge parameters to etching results. The authors form such linkages in this report. The authors measured the optical emission intensities of lines from Ar, F, S, SF x, CF 2, C 2, C 3, and CS as a function of the percentage C 4 F 8 in the gas flow, the total gas
