Influence of the Middle Magnetic Field on the Disperse Iron-Oxygen Mineral Phase Formation by Applyng the Rotation-Corrosion Dispergation Method

The purpose of this work was to investigate the process of the disperse iron-oxygen mineral phase formation by applying the rotation-corrosion dispergation method when the middle magnetic field affected the system. The rotation-corrosion dispergation method is based on the principle of iron (steel) electrode corrosion when its surface contacts either with air or dispersion medium. The constant magnetic field was influencing the system during the process of the phase formation. The magnetic field intensity was 0,6—1,9 kOe and remanent magnetic induction was 0,7—1,3 T.

Formation of ultradisperse ferrites of nickel, copper, and zinc in the iron–carbon galvanocontact system. 2. Analysis of colloidal-chemical mechanisms of ultradisperse ferrites formation in the iron–carbon galvanocontact system

This paper makes a case for colloid-chemical mechanisms of zinc, nickel and copper ferrites formation reactions, as well as composition of dispersed medium compounds, which take part in the ferriteformation process. It highlights the optimal conditions for ferrite-formation in the systems containing nickel, copper, and zinc cations.
