“…The primary disadvantages are the inflating faults, which appear as big spaces inside the granule, and the formation of capillary tension as a result of the fast evaporation of water. This stress may cause unwanted diffusion and segregation, reducing the compositional and morphological homogeneity of NPs [112,113]. Because flaws may resist annealing, the spray droplets can be frozen with liquid nitrogen and freeze-dried to maintain the desired particle size and prevent defects.…”

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.
