popup.description1
Study of physical, mechanical and operational characteristics of polymer nanocomposites filled with MFe2O4 ferrites (where M=Zn2+, Mn2+, Fe2+, Co2+, Ni2+, Cu2+) and ferrites doped with rare earth metals MReхFe3-хO4 (R=La3+, I3+, Nd3+, Sc3+) and development of methods of obtaining.

The object of research is composite radio-absorbing materials based on modified spinel ferrites, synthesis patterns, chemical and structural-phase transformations. The aim of the work is to study the physical-mechanical and operational characteristics of ferrites MFe2O4 (where M=Zn2+, Mn2+, Fe2+, Co2+, Ni2+, Cu2+) and ferrites doped with rare-earth metals МRхFe3-хO4 (R=La3+, Y3+, Nd3+, Sc3+ ) and to develop methods for obtaining them.
Research methods are vibrational magnetometry, wide-angle and small-angle X-ray scattering, physical-mechanical tests, IR spectroscopy, cyclic voltammetry, UV/Vis spectrophotometry, EPR spectroscopy. The influence of the synthesis method of nanosized spinel ferrites of the general formula MFe2O4 (M=Zn2+, Mn2+, Fe2+, Co2+, Ni2+, Cu2+) and spinel ferrites МReхFe3-хO4 (Re=La3+, Y3+, Nd3+, Sc3+) modified rare-earth metal cations on the structural and magnetic properties of the products was investigated. A set of experimental and theoretical data on the conditions for obtaining nanodispersed spinel ferrites (with different composition, structural organization and properties) by plasma, ultrasonic, hydrothermal, co-precipitation was presented. The optimal conditions for the processes were determined. Field of use: C 20.59 Production of other chemical products; M 72.1 – research and experimental developments in the field of natural and technical sciences.
