Abstract (en)

A spark plug and method of construction is provided. The spark plug has a generally annular ceramic insulator extending between a terminal end and a nose end. A conductive shell surrounds at least a portion of the ceramic insulator and a ground electrode having a ground electrode sparking surface is operatively attached to the shell. An elongate center electrode has a body extending between opposite ends. The body of the center electrode is formed of a compacted and sintered conductive or semi-conductive ceramic material. The ceramic material of the body comprises at least one oxide. For example, the body of the center electrode can be formed of a perovskite structure or a spinel structure.
