ABSTRACT:
A kiln, useful for sintering basemetal capacitors comprises an inner zone having vertically oriented gas dispersion conduits for the inlet and radial dispersion of gas and vertically oriented electrical heating elements. Each gas dispersion conduit comprises a porous or perforated inner tube for a porous or perforated outer tube concentrically positioned around the inner tube. The annular space between is filled with a porous refractory medium, such as a bulk ceramic fiber. The temperature of the inner zone is controlled by the electrical heating elements. The gas is evenly heated as it passes radially from the inner tube through the porous refractory medium and then through the outer tube. Surrounding the inner zone is a multiplicity of stacks of substantially horizontally-oriented trays on which the material or articles to be sintered or otherwise treated are placed. The circle of stacks of trays is surrounded by an outer heating zone comprising an outer ring of electrical heating elements. The outer heating zone is, in turn, surrounded by an outer wall of porous refractory insulation. The apparatus is enclosed in a water-cooled shell of heat resistant material.
