Abstract

Improvements in the production of porous aluminous bodies of great solidity, obtained by wetting and agglomeration of powdery aluminous compositions, the agglomeration being followed by activation by calcination, characterized in that at least a fraction of the particles of this powder is obtained by dehydration partially in a stream of hot gases of hydrated alumina comprising bayerite and in that the proportion of partially dehydrated alumina from this bayerite is at least 15% by weight of these compositions.
