Process for the production of nickel in the form of porous grains or pieces of any size.
It is known that metallic nickel is obtained from the reduction of nickel oxide or other nickel compounds. The latter is obtained according to the previous type of representation in finely divided form as a fine powder, which is difficult to handle and
EMI1.1
formed nickel carbonyl and from the latter the nickel is deposited on nickel shot or the like that is kept in motion.
It was also customary to mix nickel oxide or a nickel compound with syrup or the like and bake the mixture into cakes, which

and then heated in an atmosphere of hydrogen, nitrogen, or some other gas not acting on nickel, to a temperature a little below its melting point.
EMI1.3
'the one () fen and when the appropriate temperature for reducing the nickel compound has been reached in a known manner in this way, z. B. about 400 C, you can let in hydrogen or nitrogen and raise the temperature to the required level to produce the dough-like coherent metal.
Nickel prepared in the above manner is highly active and suitable for all uses in which the catalytic properties of this metal are taken into account.
