Abstract

A sintered ceramic body for a spark plug insulator has nitride or oxinite-based ceramic powder with AlN or AlON as a main component. The insulator contains magnesium (Mg), an amount of which ranges from 0.01 wt%
to 5.0 wt% when the amount the magnesium (Mg) is calculated by reducing the magnesium (Mg) to its oxidized compound (MgO). The insulator further contains a sintering additive up to 10 wt% selected from the group consisting of alkali-based earth metals and rare-earth metals in which the weight percentage of the sintering additive is calculated by reducing the sintering additive to its oxidized compound.
