Ceramic heating element

A heating element comprising:

• a preformed tubular body having a hollow cavity centrally located within, the tubular body comprising an electrically non-conductive material;
• a heat-generating component disposed within the hollow cavity, wherein the heat-generating component is optionally in direct contact with the preformed tubular body;
• an air-displacement material disposed within the hollow cavity;
• and
• at least one electrode extending into the heat-generating component, wherein the at least one electrode is surrounded by a non-metal sleeve to electrically isolate the at least one electrode from the heat-generating component.

A method of manufacturing a heating element comprising:

• forming a ceramic tubular body having a hollow cavity centrally located within;
• disposing a heat-generating component within the hollow cavity, the heat-generating component being in electrical contact with the tubular body;
• filling the hollow cavity with an air-displacement material;
• and
• disposing at least one electrode into at least one end of the ceramic tubular body, the at least one electrode extending into the heat-generating component;
• wherein the at least one electrode is surrounded by a non-metal sleeve to electrically isolate the at least one electrode from the heat-generating component.
