ABSTRACT:
A process for the manufacture of porous sintered bodies with large open pore volume and defined pore diameter. A sinterable material in the form of finely ground powder is mixed with a leachable substance. The leachable substance is in the form of powder of a defined particle size. The mixture of sinterable material and leachable substance is heated to the sintering temperature and maintained there until the sinterable mass is sintered. The mass is then cooled and the leachable substance leached from the sintered mass.
