Process and apparatus intended for hot pressing

Description is given of a hot pressing process providing homogeneous ceramic, refractory or metallic materials of uniform or composite structure with dimensions that can reach and even overstep a squared meter. In view of the setting of the materials inside a container of versatile shape then introduced into the processing module, said materials can be pre-conditionned, their chemical and mechanical insulation during sintering can be obtained, within a controlled atmosphere and the elimination of the initial heterogeneities resulting from cold pressing also obtained. A new press with a working area of large dimensions is then described
