چکیده انگلیسی
The effect of polyvinyl alcohol, PVA, on crystallite and particle sizes of strontium hexaferrite synthesized by high-energy ball milling followed by an annealing at 950â¯Â°C is presented. Results of X-ray diffraction of (100-x)SrFe12O19@xPVA (0â¯â¤â¯xâ¯â¤â¯100) composites shown the presence of strontium hexaferrite in all samples, while the crystal structure of PVA is degraded due to the mechanical energy supplied from the milling process. However, the Infrared study (FTIR) indicated that the polymeric chain kept intact. Magnetic behavior, from vibrating sample magnetometry tests, shown a waist wasp type hysteresis loop, for all the composites SrFe12O19@PVA, confirming that both materials do not generate bonds, and there is only a mixture of materials. Finally, Rietveld refinement, SEM analysis, and particle size measurement allowed demonstrating that PVA reduces the crystallite and particle sizes at nanometers scale of strontium hexaferrite synthesized.
