Abstract

An aerosol route has been used to produce ferric oxide particles which have extensive applications in the recording industry. Conventional techniques to produce the γ phase of the oxide have been reviewed and attempts have been made to produce this in an aerosol system. The important processing conditions varied were the residence time (flow rate), solution concentration, temperature history precursor material. The powders were analyzed by X-ray diffraction, Mössbauer spectroscopy and vibrating sample magnetometry. Processing conditions to obtain higher fractions of the gamma phase are discussed.
