Ceramic igniters and method for using and producing same

Ceramic igniters are provided that comprise two cold zones with an interposed hot zone, the hot zone having an electrical path length of from 0.51 cm to about 2 cm. Igniters of the invention can effectively diffuse power density throughout the igniter hot zone region, without producing isolated temp...

Zusammenfassung:Ceramic igniters are provided that comprise two cold zones with an interposed hot zone, the hot zone having an electrical path length of from 0.51 cm to about 2 cm. Igniters of the invention can effectively diffuse power density throughout the igniter hot zone region, without producing isolated temperature gradients which can lead to premature igniter degradation and failure. The invention also provides new methods for forming ceramic igniters.
