Zinc-ferrite has extensive application prospect in the fields of catalysis, environmental protection and so on. With the development of relative products towards small size, light mass, high performance and the exploitation of application field, the synthesis techniques of nano-sized zinc-ferrite has been one of the most interest research fields. After a simplified introduction to the structure, performance and application of the zinc ferrite ,in the presennt, various methods were overviewed in some detail on the preparation of nano-sized zinc ferrite in recent years, including mechano-chemical synthesis, sol-gel method, hydrothermal method, shock wave synthesis, low-temperature combustion synthesis, spray pyrolysis process, chemical co-precipitation process,etc, with the aim of speeding up the proceeding of the new upsurge in research. And the advantages and disadvantages of mentioned above were also pointed out.
