Abstract
A heating device includes a first electrode and a second electrode including a planar portion providing a support surface for supporting an object to be heated in an external gaseous atmosphere to which the object to be heated and the support surface are exposed. The second electrode is formed as an enclosure enclosing and spaced from at least a portion of first electrode to define an interior space therebetween isolated from the external gaseous atmosphere. An exhaust port provides communication with the interior space for reducing the pressure within the interior space. A power supplies current between the first and second electrodes to produce an electric discharge within the internal space, thereby heating the second electrode and the object supported thereon.
