Influence of thickness of coated layer on parameters and kinetics of mechanical activation (example of quartz processing)

This paper describes, theoretical and application aspects concerning material treatment in dinamic type mills. A model is presented that describes the influence of tickness of coated layer of ground material on the disintegrator surface or milling bodies on parameters and kinetics of mechanical activation. Application of the model to quartz milling is presented in the paper

Mechanochemical Synthesis of Silver Chloride Nanoparticles by a Dilution Method in the System NH4Cl−AgNO3−NH4NO3NH_4Cl-AgNO_3-NH_4NO_3

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

Preparation of Carbon-Copper-Silicon Nanocomposite Materials and Coatings Owing to Abrasive-Reactive Wear

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
