Magnetic properties of silicon dioxide modified in the mechanical reactor

Results of measurement of magnetic properties of silicon (quartzite) modified by organic and inorganic additions in the mill of dynamic action (mechanical reactor) in dependence on treatment duration are presented. Measurement of magnetic properties were carried out by the EPR and magnet permeability methods. Results of the EPR spectroscopy displaying, that during the mechanical and chemical treatment in the iron chloride presence and organic additions the significant structural reconstruction takes place of the silicon dioxide dispersed particles surface. It is established that relative magnet permeability value in the experiments is changing from 5 up to 10 units in dependence on of activation time and the type of applied modificator
