Crystal chemical characteristics and physical properties of ferrous minerals as the basis for the formation of functional materials

摘要

Crystal chemical characteristics and physical properties of ferrous minerals can be criteria for search and evaluation of mineral (natural) raw for the production of functional materials. Special attention will be given to new experimental methods of transformation of minerals at different methods of influence. As a probe to identify the relationship between the actual crystalline structure of the mineral and its technological properties we used the oxidation - reduction reactions of iron ore-forming minerals. We will show that the inexpensive and affordable methods of influence at ore and technological products result in the observed Fe2+ — Fe~(3+) charge transfer, which result in the increase of the conversion degree of the structure and change of magnetic properties of the substance.
