  • Oxidation of sulfur hexafluoride - ScienceDirect

    Abstract Although SF 6 is extraordinarily inert toward oxygen, reaction can be initiated by the electrical explosion of extremely small masses of platinum into SF 6 O 2 mixtures. It is shown that chemically trivial amounts of exploding metal can be effective initiators of the SF 6 oxidation.

  • Plasma etching of Si and SiO2 in SF6–O2 mixtures: Journal of

    Jun 04, 1998 · With an SF 6 ‐O 2 mixture in the absence of silicon, the final reaction products are F 2, SOF 4, and SO 2 F 2. The product distribution was unaffected by small SiO 2 substrates. When Si is etched, SiF 4 is the only stable silicon‐containing etch product and SOF 2 is formed in oxygen‐poor mixtures.

  • Myth About SF6 Gas In Electrical Equipment

    May 25, 2020 · Pure SF6 is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Legislation for chemicals does not categorise SF6 as a hazardous material.
