Abstract
Filamentary material having a core of elemental carbon covered with a coating of silicon carbide material with a thin outer layer of elemental carbon is heated in air to cause the outer layer to oxidize. The filament is then cut to segments of a desired length, bundled and the ends metallized. A tubular metal connector is crimped over each of the metallized ends of the bundle with a conductive lead extending therefrom. The bundle assembly is then mounted onto a refractory holder.
