Ag/ZnO nanocomposite powders have various applications as contact materials. There are some methods for synthesizing them such as chemical vapor deposition (CVD), co-precipitation, spray-pyrolysis, sol-gel, laser ablation and hydrothermal routes. In this study, Ag/ZnO nanocomposite powders have been synthesized by three various co-precipitation techniques. The nanocomposite powders obtained were evaluated by scanning electron microscopy (SEM), X-ray diffraction (XRD), simultaneous thermal analysis (STA), X-ray fluorescence (XRF) and energy dispersive X-ray spectroscopy (EDS). The experimental results showed that the size of the nanocomposite samples was in the range of 50-100 nm. Finally, it was found that the optimum route for preparing Ag/ZnO nanocomposite powders was the dropping funnel method.
