ABSTRACT:
A heating element assembly design and methods of densification of such designs are disclosed for radiant heating devices, specifically adapted to avoid breakage of or damage to the heating elements. The design includes a first support having a first and a second surface, the first surface being exposed directly to the atmosphere. The design further includes at least one ceramic or metal ceramic electrical terminal, having a first and a second surface; at least one ceramic or metal ceramic heating element with a diameter of up to 12 millimeters, the heating element being connected to the second surface of the terminal, and not being in direct contact with the first support so as to cushion the heating element from forces acting upon the first support. The first surface of the terminal being closer to the first support than the heating element, and adapted to absorb some of the forces acting upon the first support so as to further cushion the heating elements.
