Composite monolithic elements and methods for making such elements

A composite monolithic element for use as a hot surface ignitor or the like includes first and second regions or layers. The first region or layer comprises a low pressure ejection molded mixture of silicon carbide and silicon nitride particles or other compatible mix which will alter processing art as a resistor. This resistor includes two cold portions and a hot portion intermediate thereof. The second region or layer also includes an ejection molded mixture of silicon carbide and silicon nitride particles or other appropriate mixture, while the second layer contains the same or similar compounds as the first, the rations of the compound differ so that after processing it acts as an insulator and as a support for the first layer. These first and second layers are bonded together to form a joint free mechanically continuous structure and densified.
