Abstract

A ceramic electric resistor is proposed which can be made by means of ceramizing at least one organo-silicon polymer and at least one filler. The filler comprises at least one high-melting electrically conductive component, with the filler portion amounting to 20 to 50 vol. % relative to the solvent-free polymer-filler mixture. The specific electrical resistance can be set by varying the filler portion. The ceramic electric resistor is particularly suited as heating conductor for pencil-type glow plugs.
