Under the applied conditions the treatment by impact (jet mill) results only in relative small effects of pulverizing and in insignificant lattice disorders investigated by X‐ray diffraction. By investigations of electron spin resonance strong and weak disturbances of cubic symmetry of crystal field are detected. Impact generates increased concentrations of point defects and few dislocations in the bulk of the grains of the powder.
