Resumen

A mixture of ferrites phases containing strontium ortho/hexagonal ferrites was synthesized using chitosan as template and heat treatments. The analysis by XRD, FTIR, SEM, TEM and HRTEM showed the coexistence of the perovskite-like SrFeO_2.9 and hexaferrite SrFe₁₂O₁₉ phases. The ferrites consisted of hard agglomerates containing nanoparticles. The crystallites sizes range between 5 and 20 nm of different morphologies. A possible phase transition model is suggested.
