ABSTRACT:
A high temperature furnace formed from a stack of ceramic fiber--toroidal discs each fabricated to have an upper and lower groove for accommodating a heating coil so as to permit thermal elongation without buckling. The stacked array form a hollow cylindrical inner chamber which receives heat in the form of radiation through a window formed by removing a portion of the material between the groove and inner chamber.
