CERAMIC IGNITERS WITH SEALED ELECTRICAL CONTACT PORTION

摘要

Robust ceramic igniters include an improved sealing system which can significantly enhance operational life of the igniter. Preferred igniters comprise a conductive cold zone (14a, 14b) and hot zone (12) with higher resisitivity. A hermetic sealant material (100) covers one or more electrical connections on each cold zone thereby avoiding igniter failure resulting from electrical shorts and/or undesired oxidation.
