Abstract
In the example of coagulation of solid particles of zirconium acetylac etonate Zr(aa)(4) in a toluene-heptane supersaturated solution, an ana lysis has been made of morphological selection of aggregates during co agulation in a supersaturated medium. It has been established that in the coagulation of Zr(aa)(4) particles, stable configurations of aggre gates are selected in accordance with the principle ''equal combines w ith equal.'' As a result, aggregates of commensurate particles accumul ate in the stirred suspension. The particles in the aggregates are att ached to each other through crystallization contacts.
