초록

Exothermic reaction mixtures are electrically ignited with a low cost foil strip of two conductive strips separated by a layer of insulation. One or more holes are formed in the ignitor to create shaped spark plasma on one side and a venting plasma on the opposite side of the hole. The spark with low energy requirements is sufficient to ignite exothermic reactions for welding, casting and other uses. The ignitor may be part of reusable crucibles and molds, or expendable packages, containers, and molds, or smaller squibs for igniting larger charges. The i...
