摘要

Powders of strontium hexaferrite (SrFe12O19) were prepared by the proteic sol-gel process using coconut water as a precursor. X-ray diffraction (XRD) measurement showed the formation of SrFe12O19 with a small amount of the hematite for the sample calcined at 1000 degrees C with Fe/Sr = 12. Rietveld refinement disclosed that this sample had 87.56% of the SrFe12O19 and 12.44% of Fe2O3 and the values for R-p, R-wp and chi(2) were 4.28%, 5.93% and 1.71, respectively. The magnetic properties were M-s = 64 emu/g, M-r/M-s, = 0.55 and H-c = 1.4 kOe for a crystallite size of 57 nm. (c) 2006 Elsevier B.V. All rights reserved.
