The final asymptotic stage of sol aging processes governed by the joint action of coalescence (Ostwald ripening) and coagulation (agglomeration) is considered. A self-similar solution of the kinetic and balance equations is obtained for a simple model example. The largetime particle size distribution density is shown to be essentially different from that due to coalescence alone in accordance with the conventional theory by Lifshitz and Slyozov.
