Fast Prepared Ni-Al2O3 Nanocomposite Through Solution Combustion Synthesis

Abstract

Solution combustion synthesis (SCS) is a well-known method for fabrication of different materials such as oxides and composite materials in an extensive range. In this investigation, solution combustion synthesis is used for fabrication of Ni-10 wt% Al2O3 nanocomposite. Nickel and aluminum nitrates, urea, and distilled water are used as oxidizer, fuel, and solvent, respectively. The results show that if the fuel to oxidizer ratio exceeds the stoichiometric ratio, the combustion temperature increases. However, introduction of graphite to the solution could conduce to the reduction of the combustion temperature. With the addition of an auxiliary material, graphite, so a nickel oxidation is postponed, Ni-Al2O3 nanocomposite is produced only in one step.
