Abstract
Presented here is a simple, inexpensive approach to aggregating colloi ds into hierarchically structured spherical particles. Successive aggr egation steps are used to assemble a particle that is self-similar on two size scales and is permeated by an ordered pore network with a bid isperse size distribution. The structure of the micro- and macropore n etworks as well as the mechanical integrity of the structure can be co ntrolled by varying sintering conditions. (C) 1996 Academic Press, Inc .
