Synthesis of alumina reinforced nanostructured α-brass by mechanochemical reduction of CuO and ZnO with Al and C

Mechanochemical synthesis of tungsten carbide nano particles by using WO3/Zn/C powder mixture

“…Researchers have shown that carbothermic reduction reactions can be activated if the aluminothermic reduction of some metal oxides like WO 3 , CuO, and ZnO occurs in SHS mode. Other wise the gradual mode of aluminothermic reaction would not activate the carbothermic reduction reactions [11,18,19,23]. So with regard to these lines carbothermic reduction reactions cannot occur in this system, because the reactions will propagate gradually (T ad = 1503.15 < 1800 K).…”

“…Additionally, the activation energy of the aluminothermic reaction was calculated to be substantially reduced with milling time, which was attributed to the increase of Al-ZnO interfacial areas and progressing formation of nucleation sites during aluminothermic reactions [7]. Not surprisingly, BM has been widely applied in various materials to obtain nanocrystallites [2][3][4] and nanocomposites [1,[7][8]. However, there are some requirements for the reaction to be self-sustaining.…”
