Abstract
An igniter () includes an outer insulator () formed of an outer ceramic material hermetically sealed to a conductive core (). The conductive core () is formed of a core ceramic material and a conductive component, such as an electrically conductive coating applied to the core ceramic material or metal particles or wires embedded in the core ceramic material. The conductive core () is typically sintered and disposed in the green outer insulator (). The components are then sintered together such that the outer insulator () shrinks onto the conductive core () and the hermetic seal forms therebetween. The conductive core () fills the outer insulator (), so that the conductive core () is disposed at an insulator nose end () of the outer insulator () and the electrical discharge () can be emitted from the conductive core (), eliminating the need for a separate firing tip.
