Abstract:The Ni-Al alloy containing Cr, Fe additives were prepared as Raney Ni catalyst by high energy milling. The size and surface state of Ni-Al alloy powder were studied by particle size analyzer and sanning electron microscopy, the structure was analyzed by XRD and M ssbauer methods. The results showed that after a high-energy milling (HEM), the Ni-Al alloy transforms to a nano-scale NiAl structure with rich Al. By annealing the alloy, a metastable Ni2Al3 phase can be obtained.

 

Key words: Raney nickel catalyst; nano-crystal; high-energy; milling
