In this talk I will describe the stochastic model of cluster-cluster 
aggregation that is used to account for the behavior of colloids.  
During my doctoral thesis I developed four different models of colloidal 
aggregation of binary mixtures.  Two of these models are related to 
heterocoagulation, and the other two models describe the growth of 
fractal aggregates in the presence of impurities.  Properties of both 
the sol regime and the gel regime of these binary mixtures will be 
discussed.
