| description | A method and apparatus for decreasing the radial temperature gradient in CVI/CVD furnaces is provided. The apparatus may comprise a graphite susceptor disposed within a vessel. Porous structures may be stacked within the graphite susceptor. The stack of porous structures may form a circular shape proximate a radially inward surface of the graphite susceptor. Graphite panels may be disposed within the graphite susceptor. The graphite panels may be located proximate a radially inward surface of the porous structures. The graphite panels may radiate heat radially outward and towards the graphite susceptor. Reactant gas may be flowed into the graphite susceptor. |
