Ceramic igniter
摘要:
New ceramic resistive igniter elements are provided that comprise a first conductive zone, a resistive hot zone, and a second conductive zone, all in electrical sequence. In preferred igniters, at least a substantial portion of the first conductive zone does not contact a ceramic insulator. Preferred igniters of the invention have a rounded cross-sectional shape for at least a portion of the igniter length.
