The CsCl structure of the Raney nickel catalyst obtained from mechanically alloyed nickel aluminides

Mechanically alloyed nickel aluminide of composition Ni 35Al 65 retains its CsCl structure after being treated with 20% KOH solution. The Raney nickel catalyst thus obtained was identified as having a CsCl-type structure. Annealing of this metastable material at 120–150°C led to the formation of a c...

Description
Summary:Mechanically alloyed nickel aluminide of composition Ni 35Al 65 retains its CsCl structure after being treated with 20% KOH solution. The Raney nickel catalyst thus obtained was identified as having a CsCl-type structure. Annealing of this metastable material at 120–150°C led to the formation of a cubic nickel structure. This phase transformation was accompanied by the appearance of strong ferromagnetism.
