Abstract: A monolithic, multi-layer heating element forms the high temperature tip of a glow plug assembly. The heating element includes a conductive core which is surrounded by an insulator layer, which in turn supports a resistive layer. An optional conductive jacket can surround the resistive layer. These layered components are pre-formed in prior operations and then assembled one into the other to form a precursor structure. The precursor structure is transferred to a die, where it is compressed to form a so-called green part having dimensional attributes proportional to the finished heating element. The individual layers remain substantially intact, with some boundary layer mixing possible to enhance material-to-material bonding. The green part is sintered to bond to various materials together into an essentially solid mass. Various finishing operations may be required, following which the heating element is assembled to form a glow plug.

Abstract: A spark plug which includes a center electrode metal shell and an insulator disposed therebetween utilizes for the insulator or ceramic with improved high temperature electrical properties which includes alumina in an amount between about 90 and about 99% by weight, a zirconium containing compound in an amount between about 0 and about 1% by weight, and an oxide mixture in an amount between about 1 and about 10% by weight. The oxide mixture includes a glass former, a network modifier and alumina in an amount between about 16% and about 40% by weight after firing, wherein the molar ratio of the glass former to the network modifier ranges between about 0.8:1 and 1.2:1. The ceramic insulator is particularly adapted for use as an insulator in a spark plug to provide improved dielectric strength and shunt resistance of greater than one 1000 megaohms at 1000 degrees Fahrenheit, so as to reduce the shunting of the spark plug and thereby improve the quality of the spark generated by the spark plug.
