Nikel-Znic ferrites with chemical formula Ni1-xZnxFe2O4 for (x:0.00 , 0.5 and 1) were synthesis by chemical co-precipitation method at various annealing temperatures (27°C,300°C,600°C,900°C, 1200°C) for (4h). The samples were examined via X-ray diffraction patterns. The XRD pattern confirm the formation of face centered cubic structure (fcc) for all samples. The particle size, lattice parameter, theoretical density and  porosity were also measured by X-ray diffraction, and bulk density. It is noted that granular particle size increases with increasing annealing temperature, while decreasing lattice constant, theoretical density and porosity with increasing annealing temperature. The homogeneity, regularity, particle size and the roughness of sample surfaces were calculated using atomic power microscope technique.
