Synthesis Routes for Ferrites and Their Impact on the Properties of Ferrites

Abstract

Nano ferrites have piqued interest owing to their numerous uses in biomedical, wastewater remediation, and electronic devices. This chapter is primarily concerned with the various fabrication techniques for ferrite nanoparticles. This chapter presents various methods used for ferrites preparation with distinctive examples, their advantages as well as limitations in detail. The fabrication techniques used to achieve ferrites nanoparticles of various structures and morphologies, such as hydrothermal, microemulsion, solvothermal, solution combustion, microwave, chemical vapor deposition, sol-gel, chemical bath deposition, or wet chemical synthesis, sonochemical, thermal decomposition, and electrochemical methods, are briefly described. This chapter summarizes the recent work on the influence of synthesis techniques on the properties of ferrites in nanoform. Ferrites belong to the materials which are a potential candidate for widely spread applications. Keywords Ferrites • Nano materials • Synthesis techniques 1 IntroductionThe three major targets of magnetic nanomaterials are synthesis, knowledge of novel advanced materials, and relationships between them. Nanomaterials are those materials whose particle size lies between the range of 10-100 nm in at least one or more dimensions, as defined by their nanometric equivalents. A large number of atoms are present at or near the surface of particles at this length scale, giving the materials their specific properties. Nanomaterials have a high surface-to-volume ratio which

“…In nanoscience, nanotechnology deals with the study of nanoparticles, nanorods, nanotubes, nanofibers, nanospheres, etc, with varying sizes, but one dimension is less than 100 nm. The nanomaterials pull towards versatile physical and chemical properties due to the size and shape variation, leading to multipurpose applications and optical, magnetic, or electrical properties [3][4][5]. Nanoparticles have distinguished characteristics from bulk materials only by the reduction in size, namely, chemical reactivity, energy absorption, and biological mobility in physics, chemistry, and biology, which lead to combination in materials science [6].…”
