Hot zone igniter

An igniter for igniting combustible gases in a hot zone, such as in a solid oxide fuel cell, comprising a subassembly including an electrical resistance heating tip comprising SiC, metal leadframe clips formed of a nickel-based superalloy and attached to the heating tip, wire leads formed of a nickel-chromium alloy and connected to the leadframe clips for supplying electric current to the heating tip, and a nickel-based braze alloy comprising palladium and cobalt for connecting the leadframe clips to the heating tip and to the wire leads; an alumina ceramic body for receiving the brazed subassembly; and a potting compound comprising zirconia for potting the subassembly into the alumina ceramic body.
