摘要
The thermal behaviour of the polynuclear coordination compounds Fe12-xSr(malic) (19-1.5x)]. 18H(2)O and [Fe12-xSr(gluc)(19-1.5x)]. 20H(2)O precursors of strontium hexaferrite was investigated, and a decomposition mechanism is proposed. A pure hexaferrite with a mean crystallite size value of about 250 Angstrom was obtained after 5 h calcination at 800 degrees C of the gluconic precursor (x=1.5).
