Electron Paramagnetic Resonance in the Research of Defect Formation and Thermal Processes During Grinding of ZnO Powders

摘要

This wok shows some posibilities for using electron paramagnetic resonance in an experimental study of hte role of mechanothermal effects in the formation of defect structures in dispersed systems during prolonged mechanical treatment of ZnO powders. TheuseofEPR for this purpose is based on the known fact that initiation of a number of paramagnetic centers occurs during mechanical treatment of some materials, Such centers can serve as EPR-sondes of different thermal processes appearing during mechanical treatment of systems
