    Effect of annealing on the microwave-absorption properties of Ni/Al2O3 nanocomposites

    Ni/Al2O3 nanocomposites were prepared by the mechanochemical synthesis method. The annealing process enlarges the grain size of both the metal Ni and insulating Al2O3 in the as-milled nanocomposite and leads to a...
