The aggregation kinetics of impurities in KCl:Mn$^{2+}$ and KCl:Mn$^{2+}$, Pb$^{2+}$ crystals has been studied. For decay measurements of Mn$^{2+}$ – cation vacancy dipoles the EPR method was applied. The results were evaluated assuming kinetics of the I,II and III order, taking into account and neglecting the reverse reaction. Calculations show that aggregation kinetics can be described using the first order with some contribution from of higher orders. This lead to a conclusion that the aggregation processes occurs in few ways.
