Özet

The study of synthesis, charactrerization and application of silica-magnetite nanocomposites was presented. The temperature dependence of the static magnetic susceptibility of pure magnetite and silica-magnetite nanocomposite was measured and the hysteresis loop was collected at 2.5 K. The coercivities and reduced remanences were also measured and the saturation magnetization was centered at 88 emu g-1 at 2.5 K and around 82 emu g-1 at 300 K. All magnetite and silica-magnetite samples were fully characterized for their relative chemical composition using Fourier-transform infrared, XRF and thermo-gravimetric analysis.
