The aim of this research prepared and studying some structure properties of (ZnO)0.4 (ZrO2)0.6 nanocomposite Prepared by Powder metallurgy Technique. The structural and surface morphology of the nanocomposite were examined by means of X-Ray Diffraction and scanning electron microscopic (SEM). The particle size calculations were done using XRD Scherer’s formula (15nm),and sample contain a mixture of the monoclinic, tetragonal hexagonal structure.
