| 1 | Manufacture of Raney Ni catalyst with metastable Ni_2Al_3 by high energy milling显示文摘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 Mssbauer 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 Ni 2Al 3 phase can be obtained. | Teng Ronghou(滕荣厚) 1, Sun Shijie(孙世杰) 1, Liu Silin(刘思林) 1, Liu Xuequan(柳学全) 1, Ma Ruzhang(马如璋) 2,Liu Tao(刘 涛) 3 1.
