Abstract

Polycrystalline BaFe12O19 has been synthesized by pyrolysis of an aerosol produced by ultrahigh frequency spraying of a solution. Two precursor solutions have been used in order to study its influence on the formation temperature of the barium hexaferrite and on the microstructural and magnetic properties. The relationship between in situ temperature, pyrolysis precursor, and textural and magnetic properties of the products obtained is discussed.
