Abstract

In this study, we produced strontium hexaferrite magnets with different metal dopped via solution combustion synthesis technique using strontium nitrate (Sr(NO3)2), iron (III) nitrate (Fe(NO3)3) and citric acid (C6H8O7). Calcium nitrate tetrahydrate (Ca(NO3)2.4H2O), chromium (III) nitrate nonahydrate (Cr(NO3)3.9H2O) and manganese (II) nitrate tetrahydrate (Mn(NO3)2·4H2O) were used as additives in the production of dopped magnets. Magnets produced during the studies were annealed at different temperatures and various analyzes were made. X-Ray Diffraction (XRD) was used to determine the phases in strontium hexaferrite (SrFe12O19), Master Sizer analysis to determine grain sizes, and Fourier Transform Infrared Spectrometer (FTIR) analysis to determine chemical bonds.
