  • Ceramic heating element
    Patent number: 11457513
    Abstract: A heating element including a preformed ceramic tubular body having a hollow cavity centrally located within, a heat-generating component disposed within the hollow cavity, and an air-displacement material disposed within the hollow cavity. The preformed ceramic tubular body is one of aluminum oxide, aluminum nitride, and silicon nitride ceramic. The heat-generating component may be in electrical contact with the ceramic tubular body. The air-displacement material is magnesium oxide. Further, the heat-generating component and the air-displacement material are disposed within the hollow cavity of the preformed ceramic tubular body by way of at least one of a vibrating fill and a centrifuge for compaction.
    Type: Grant
