Nanoferrite Composites:

Abstract

Ferrites are a large group of oxides with amazing magnetic properties and their nanomaterials are effectively studied because of their greater physical properties. Nanoferrite composites have gained great attention or interest because of their number of applications in magnetic, optical, wastewater treatment, electronic, and catalyst fields. In this chapter, we discuss the crystal structure of ferrites, their properties, and the most-used synthesis methods of nanoferrites, such as co-precipitation, hydrothermal, sol-gel, thermal decomposition, etc. The characterization of nanoferrites like size and shape, surface morphology, magnetic properties, etc. are discussed. Also, we discuss how nanoferrites work as a catalyst in the thermal decomposition of ammonium perchlorate. Nanoferrites’ composites have excellent catalytic properties on the thermal decomposition of ammonium perchlorate. Ammonium perchlorate (AP) is widely used as an oxidizer in composite solid propellants (CSPs). Composite solid rocket propellants can be improved by adding nanoferrites, since they increase the rate of decomposition of AP.
