摘要： The invention relates to a process for the production of sintered porous bodies, to porous bodies produced correspondingly using the process, and to their use. With the solution according to the invention, sintered bodies which achieve improved properties, such as an increased surface area, deformability of the structures at room temperature or modification of the initial pore volume, are to be produced. To this end, at least one sintering-active powder which forms at least one intermetallic phase or mixed crystals is applied to the surface of a porous basic body. Heat treatment is to be carried out subsequently, in which intermetallic phases or mixed crystals which increase the specific surface area can be formed.
