Improvement in the mechanical strength of the supports of porous catalysts is increasingly needed by the refining industry because of the high stresses induced by the exploitation of catalysts. Drying is known to be a critical process for mechanical strength during the preparation of supports, leadi
Using diffusing-wave spectroscopy, we followed the aggregation and gelation of concentrated (30 vol%) alumina suspensions. The suspensions were destabilized by either shifting the pH to the isoelectric point or by increasing the ionic strength. Both effects can be achieved continuously and homogeneo
