Synthesis of nanoparticles of various compositions and exciting properties, sizes
and a variety of morphologies is a vast expanding subject of nanoscience because of their
very interesting and a variety of applications. Preparation of nanoparticles with remarkable
characteristics along with desired size and morphology in a precisely controlled and
reproducible manner is an art by itself. Solvothermal/hydrothermal based synthetic
methods are economical and environmental friendly because they are carried out in a close
system avoiding toxic solvents and reagents. In this chapter, solvothermal/hydrothermal
syntheses of magnetic nanomaterials especially iron oxide nanoparticles and other
nanostructures, metal ferrites and mixed metal ferrites and composites have been reviewed.
Keywords: Hydrothermal, iron oxide, metal ferrites, metal oxides, mixed metal
ferrites, nano-composites, nanomaterials, nanoparticles, solvothermal
