Abstract:
This paper describes the effect of controlling sintering temperatures on microstructure development of strontium hexaferrite from millscale derived. The sample was prepared by the recyling the waste steel-making product from Malaysina steel factories. Using a Curie temperature separation technique, the Wustite FeO contained in the millscale was separated by Curie temperature separation technique using deionized water at 90 °C/100 °C in the presence of 1T external field. The wustite was then oxidized in air at 400 °C/500 °C/600 °C for 10 hours. And XRD phase analysis showed that a very high percentage of Fe2O3 was present in the final powder preparation. A conventional processing method was then done to prepare hexagonal SrFe12O19 pallet shaped samples. The samples were sintered at different temperatures (1200 °C, 1250 °C, 1300 °C and 1350 °C) in air for 10 hours. The effect of controlling sintering temperature on orientation grain growth (0.3μm-0.7μm) in SrFe12O19 was confirmed by the microstructure surface scan using SEM and was in good agreement with the XRD analysis based on the peak intensity of the (107) plane. Analysis of samples was also done on grain size, Curie temperature and density.
