Abstract

A tubular heating element (10) having a metal tube (12) filled with a ceramic material (14). The metal tube has a near zero or slightly positive temperature coefficient of resistance. In an alternative embodiment, a wire (16) is coaxially supported within the metal tube (12) by the ceramic material (14).
This wire may be used to stiffen the tubular heating element (10) or may be used as an electrical conductor.
