Abstract

A spark plug is provided having a resistor. The resistor is made from resistor glass material containing an alkali free barium alumino-silicate glass mixed with mullite. In one embodiment, the resistor is a 15 to 30 wt % alkali free barium alumino-silicate glass and 10 to 25 wt % mullite. The resistor material provides for a greater processing kiln temperature range with reduced resistor variability and improved durability performance.

Claims (4)

1. A spark plug comprising a resistor made from a mixture of alkali free barium alumino-silicate glass and mullite wherein the alkali free barium alumino-silicate glass is comprised of MgO at 2.0 wt %, Al2O3 at 11.3 wt %, SiO2 at 53.5 wt %, CaO at 12.0 wt %, and BaO at 20.5 wt % in composition.

2. The spark plug of claim 1 wherein the resistor is made from 15 to 30 wt % alkali free barium alumino-silicate glass.

3. The spark plug of claim 2 wherein the resistor is made from 10 to 25 wt % mullite.

4. The spark plug of claim 1 wherein the resistor material containing alkali free barium alumino-silicate glass is processed in a kiln at a processing temperature between 1650° F. and 1850° F.
