Abstract: Theoretical and experimental investigation of the solid-phase mechanochemical synthesis of nanoscale desired product on the basis of dilution of the initial powder mixture of reagents with another product of the exchange reaction was carried out. Optimal molar ratios of the mixture components providing impact-friction contacts of reagent particles and excluding aggregation of nanoscale particles of the desired reaction product were calculated basing on the three-modal particle size distribution. A deduction of the kinetic equation for the mechanochemical synthesis of nanoparticles by means of dilution is presented. The obtained theoretical results agree with the results of experimental investigation of the kinetics of mechanochemical synthesis for TlCl nanoscale particles. Experimental estimation of the mass transfer coefficient was carried out for the first time and the dynamics of changes in the size of nanoparticles depending on the time of mechanical activation was established for a ball planetary mill AGO-2.
