        Addition of NaOH to a mixture of nitrates or chlorides of Ni and Al rich in Ni salts resulted, after washing and drying, in the formation of a hydroaluminate of Ni.  An X-ray study was made of these types of compounds.  The X-ray results were consistent with a structure composed of layers of hydroxyl ions and layers of metallic ions.  The role of the Al might be to stabilize this type of structure by substitution for a small number of Ni ions.  Such hydroaluminates of Ni have been used in the preparation of catalysts for the Fischer-Tropsch synthesis.
