Abstract
A furnace for isostatic hot pressing includes a furnace compartment contained within a pressure chamber, the compartment being surrounded by a insulating sheath, comprising a cup-shaped insulating portion. Such portion comprises a supporting tube of graphite surrounded by a plurality of layers of carbon or of graphite fibers. Convection-preventing layers of graphite foils are disposed between the layers and between the innermost layer and the tube. The layers are maintained pressured against the tube and against one another by a plurality of surrounding graphite strands. A plurality of cover discs of foamed graphite having graphite foils on one side thereof are seated against upper ends of the layers and of the tube, the foils on the discs extending upwardly to lie against the peripheral end walls of the discs.
