Mn0.49Zn0.48Fe2.06O4ferrite nano-powders were prepared by co-precipitation method and pressed into ring samples by dry pressing to study the effect of sintering atmosphere, sintering temperature and heating rate on properties of Mn-Zn Ferrites. X ray diffraction (XRD), scanning electron microscopy (SEM), and vibration sample magnetometer (VSM) were used to characterize properties of the obtained samples. It was shown that the samples sintered in nitrogen contained no impurities with cubic spinel structure. The samples sintered at 880°C with heating rate of 5°C/min had a density of 4.82 g•cm-3, high quality factor Q of 57 at a frequency of 2MHz, high saturation magnetization Ms of 90.02emu•g-1.
