ZnO nanowires were synthesied at 1380C from ballmilled ZnO powders by a thermal evaporation procedure with argon carrier gas without any catalysts. Scanning electron microscopy revealed that the typical diameter and length of the ZnO nanowires are in the uniform ranges of 15 to 40 nm and 10 to 70 m respectively.

From the SEM images and EDS analysis it is shown that 15 h BM duration is the optimum milling time for this formulation. The hardness and brittleness of Fe and Co prevent shorter ball milling hours to obtain uniform particle distribution. On the other hand longer ball milling hours causing agglomeration and thus creating porous surface.
