“…There are no of synthesis methods were used in to prepare spinel ferrite nanoparticles but the sol-gel auto-combustion fascinates great attention of investigators. Due to their advantages such as, environmental friendly rout, cost effective, minimization of synthesis step, reactions with little non-toxic byproducts, high yield it does not require specialized equipment [2]. On account of their excellent properties they have been widely used in numerous applications viz.…”

Nickel ferrite NiFe2O4 nanoparticles were synthesized through sol-gel auto combustion method using dextrose as a fuel. The prepared nanoparticles were investigated for their structural, optical and magnetic characterization. X-ray diffraction (XRD) revealed the development of single-phase cubic spinel with crystallite size of 14 nm. The optical study showed that the compound has an optical band gap 2.26 eV. The magnetic properties were investigated through M-H hysteresis curve. The photocatalytic activity of nickel ferrite was studied based on the degradation of methylene blue (MB) as a model compound, where the results showed that prepared nanoparticles possess a good photocatalytic activity.

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.
