This study presents the results of the synthesis of silver chloride nanoparticles dispersed within ammonium nitrate matrix via displacement mechanochemical reaction NH_{4}Cl + AgNO_{3} + zNH_{4}NO_{3} = (z+1)NH_{4}NO_{3} + AgCl at z = z_{1}= 7.22 and z = z_{2}= 3.64. The intermediate compound, NH_{4}Ag(NO_{3})_{2}, was identified after mechanochemical processing of studied system. Use of simultaneous thermogravimetry and differential scanning calorimetry provide a new means for preparing silver chloride nanoparticles in their free form by thermal treatment.

We will focus on the important aspect of mechanical activation by grinding in a mill, namely, nanoscale wear of the treated substances and of the milling tools. A new technology called abrasive-reactive wear has been developed that utilizes wear debris as an integral component of the reaction system rather than treating it as a harmful impurity. This technology is applied to the processing of low-grade diamond and silicon by cupric milling tools. Abnormal influence of graphite on abrasive wear degree is established.
