Low Temperature Synthesis of Micro-sized NixAly Alloy Powders for Applications of Catalysis |
초록 |
Micro-sized NixAly alloy powders were synthesized through a low-temperature chemical alloying method using mixtures of Ni and Al powders as well as AlCl3 as an activator in a quartz batch reactor at temperatures of 400 to 500 °C without sintering. Five Ni-Al alloy powders, Ni3Al (Ni-13.3wt%Al), Ni5Al3 (Ni-21.6wt%Al), NiAl (Ni-31.5wt%Al), Ni2Al3 (Ni-40.8wt%Al), and NiAl3 (Ni-58wt%Al), all thermodynamically stable at the aforementioned temperature range, were synthesized without significant changes in morphology, compared to the starting Ni powder. These as-synthesized NixAly alloys were characterized using different analytical techniques including particle size analyzer, X-ray diffraction and field emission scanning electron microscopy in conjunction with energy dispersive X-ray spectroscopy to confirm the formation of single phase NixAly alloys powder. These as-synthesized NixAly alloy powders will be promising template materials to manufacture nickel skeletal catalysts with high surface area for different chemical reactions. |
