Beschreibung
Zusammenfassung:	A composition for forming an electrode for use in a torch jet spark plug is provided. The composition comprises a ceramic material, ceramic particles, and an electrically conductive material. The ceramic particles are dispersed within the ceramic material. At least some of the ceramic particles have a predetermined size. This predetermined size is at least as large as the thickness of the finally formed electrode. The electrically conductive material is capable of being manipulated to form ribbons around the ceramic particles and of being sintered to form the electrode. The resultant electrode has good resistance to explosive erosion mechanisms, which consequently increases the life of the torch jet spark plug.
