Abstract:
A process for manufacturing a porous object with regulated porosity containing at least one granular material having a particle size of at least 0.1 mm, said process comprisingplacing said at least one granular material into a mold having (1) dimensions that are the same as the object to be manufactured and (2) at least one evacuation opening of a size less than the particle size of said at least one granular material, said at least one evacuation opening located at the bottom of the mold; pouring a liquid-phase binder into the mold at the top of the mold; distributing evenly said binder by gravity between the grains of said at least one material; and while said binder is being distributed, draining off excess binder through the evacuation opening using suction means to accelerate distribution of said binder and to form said porous object.
