ABSTRACT:
Improved conductive elements for direct exposure to reactive ambients. The conductive articles are fabricated from bodies of alpha silicon carbide comprising a minor fraction of homogeneously dispersed conductive particles. The bodies may have a sufficiently low electrical resistivity so that they may be used as heaters for direct contact with workpieces at high temperatures.
