Abstract

Synthesis of Ni0.4Zn0.6Fe2O4 spinel ferrite and microwave adsorption of related polymer composite

Highlights

  • Ferrites-spinels and orthoferrites of rare earth elements remain relevant objects of research for many decades due to their wide application in many areas of modern science and technology [1,2,3]

  • The data obtained indicate that the initial pre-ceramic powder and the ceramics obtained on its basis are single-phase samples of Ni0.4Zn0.6Fe2O4 (JCPDS # 08-0234 ) without impurities

  • In the case of a sample sintered at a temperature of 1000 ◦C, a large number of voids between grains are observed, the size of which is in the submicron range

Summary

Introduction

Ferrites-spinels and orthoferrites of rare earth elements remain relevant objects of research for many decades due to their wide application in many areas of modern science and technology [1,2,3]. Polymers are not subject to corrosion and are much lighter than oxide systems, but they have much higher insulation and low stability of electromagnetic parameters [21] This problem can be solved by adding magnetic particles to conducting polymers [22]. The use of ferrites as a radio-absorbing material places high demands on the stability of the magnetic and electromagnetic characteristics of the final product, which is difficult to achieve when using classical methods of production [24]. One of the promising methods for obtaining nanostructured complex oxide systems is the solution combustion method, which has shown its efficiency in the production of spinel ferrites and orthoferrites of various compositions [25,26,27,28]. The resulting product was tested using a rectangular waveguide transmission line method in the X-band (8.5–13 GHz)
