  • US4959101A - Process for degassing aluminum melts with sulfur

    Sulfur hexafluoride is a similar to halocarbon 12 in that it is a nontoxic, noncorrosive gas. The time threshold limit value-TWA ("TWA" stands for "time weighted average") for sulfur hexafluoride is 1000 ppm. As with halocarbon 12, it can replace the oxygen in the air so there is a danger of suffocation.
