Recent Advances in Processing of Hard Ferrites

Abstract

We plan to discuss possible fabrication approaches for hard ferrites, which are well-known for their vast range of applications and uses. We've covered all six varieties of hexagonal ferrites in this chapter: M-type, Z-type, Y-type, W-type, X-type, and U-type hexa-ferrites. Hexaferrites are ferromagnetic materials, and their properties are entirely determined by the intrinsic structure of ferrites. The numerous synthesis procedures for hard ferrite nanoparticles are the focus of this chapter. This chapter describes in detail the different processes for preparing hard ferrites, including examples, advantages, and limitations. Solid-state, combustion, hydrothermal, microemulsion, solvothermal, solution combustion, biosynthetic approach, microwave-assisted combustion, sol–gel, co–precipitation, or laser pyrolysis, sonochemical, thermal decomposition, and reverse micelle processes are briefly explained. The influence of synthesis procedures on the characteristics of ferrites in nanoform is summarised in this chapter.
