Resumen:
BaFe12O19 fine particles were synthesized after milling an intermediate step precursor in the sol-gel method. The milling process results in a better transformation of the initial mixture into BaM ferrite compared to the non-milled precursor heat treated at the same temperature. Microstructural study by SEM of the modification of the intermediate step precursor upon milling is carried out. The observed structural modifications are discussed with regards to its influence in the final obtained BaM hexaferrite.
