Beschreibung
Zusammenfassung:	Disclosed herein is a powder of discrete, macroporous, microspheroids, each having an average diameter in the range of 2 to 50 microns and each composed of a plurality of large colloidal particles joined and cemented together at their points of contact by 1 to 10% by weight of non-porous, amorphous silica. These microspheroids have a high degree of mechanical stability and a surface area between about 80 and 110% of that of the large colloidal particles. Also disclosed is a process for the manufacture of this powder.
