Nanostructured materials have been noted a massive scientific progress and industry development over the last few decades. The nanostructured materials can be produced from ceramics, metals, polymers, etc. The nanocomposites are the one type of nanomaterials. The nanocomposites with metal matrix and nanoparcicles coating have been prepared by means of electrodeposition process. The chemical composition is one of the most important factors for prediction of mechanical and physical properties of nanomaterials. The polycrystalline nickel reinforced by SiO2 nanoparticles was synthesized by electrodeposition method. The chemical composition of Ni-SiO2 nanocomposite was studied by two different methods. The Scanning Electron Microscopy fitted with by EDX detector and Atomic Absorbance Spectroscopy was used for determination of exact content of SiO2 in nanocomposite. The sample preparation was provided by microwave-assisted digestion.
