摘要： New coaxial ceramic heating elements and methods for manufacture wherein a conductive core region extends into a resistive hot zone at the distal end of the heating element, thereby moving the interface between the core conductive region and the resistive hot zone away from the distal tip of the heating element. Methods comprise bringing together a pre-formed or hardened zone of material with a zone of one or more materials having flow, curing, gelling, drying or otherwise solidifying or hardening the material having flow, and sintering to thereby forming an integral coaxial heating element.
