| Abstract: | Nanocrystalline particles of barium ferrite magnetic material have been prepared by co-precipitation route using aqueous and non-aqueous solutions of iron and barium chlorides with a Fe/Ba molar ratio of 11 and subsequent drying-annealing treatment.Water and ethanol/water mixture with volume ratio of 3:1 were used as solvents in the process.Coprecipitated powders were annealed at various temperatures for 1 h.FTIR(Fourier transform infrared spectroscopy),XRD(X-ray diffraction),DTA/TGA(differential thermal an... |
