    摘要: Provided are novel azeotrope-like compositions of SF6 and N2O, as well as methods of using the same. Also provided are methods of using SF6 compositions, including azeotrope-like compositions, including a method for suppressing an electric arc or corona discharge and a method for flame suppression. Further provided are electrical devices using such SF6 compositions as a dielectric insulating gas and rigid closed-cell foams having such SF6 compositions within the cells, wherein the foam is both thermally and electrically insulative.

    摘要: The present invention provides compositions that are intimate mixtures of hydrogen fluoride and a polyacrylate-polyacrylamide cross-linked copolymer. The compositions of the invention are less hazardous and, therefore, more conveniently stored, transported, and handled in comparison to pure hydrogen fluoride. Further, the hydrogen fluoride may be readily recovered from the compositions of the invention for use.
