Abstract
An ignitor for fuel gas burners formed of a plurality of spaced parallel filaments of SiC coated Carbon (C) high temperature brazed with Chromium Silicide in grooves provided in a refractory base block of Aluminum Oxide and Silicon Oxide. Terminal posts of IVIoSi are embedded in the high temperature braze. Stainless steel lead attachment pads are nickel-chrome brazed to the posts at a lower temperature. Removable notched graphite bridges and graphite hold-down blocks position the filaments during the high temperature brazing.
