Ferrite polymer composites are progressively taking the place of traditional ceramic magnetic materials due to their superiority and lower cost. They are utilized to treat hard water, have incredible stability, can be recycled efficiently, and may be used multiple times without losing their qualities. Additionally, they might make good materials for sensors, microwave absorbers, and other aeronautical uses. The creation of ferrite polymer nano-composite and their uses are the primary topics of this review. A brief discussion of the various types of ferrite nanoparticles, their synthesis processes, properties, and applications has also been provided. Due to the vast size of the area, every effort has been made to integrate the original sources that provide greater detail about each specific application. Ferrites are typically known for their porosity in its physical and chemical absorbance qualities, all of which are readily adjusted by selecting the suitable synthesis pathways and parameter such as the morphology pH of a solution temperature during sintering, amount of doping and co-doping particles, or composites of nanoparticles. The research on ferrites' evolution as a gas sensing component over the last 20 years is compiled in this publication.
