Abstract
Ceramic igniters are provided that comprise at least three zones of differing electrical resistance, preferably in sequence a first conductive zone of relatively low resistance, a power booster or enhancement zone of intermediate resistance, and a further hot or ignition zone of high resistance. Igniters of the invention can provide extremely high speeds (low time-to-temperature).
