The salt-melt method was adopted to prepare high-performance Sr ferrite without further pulverizing. The reaction path, particles size and magnetic properties have been investigated by using high-purity starting raw materials to synthesize Sr ferrite by replacing SrSO 4 with celestite. The magnetic properties are compared with those of materials prepared by the ceramic process. Due to the lower reaction temperature, no further pulverization is needed and due to low-cost minerals, the process should be more economical than the conventional ceramic process.
