ABSTRACT
The preparation of nanosize cobalt and nickel metal powders and powders
of solid solutions of cobalt and nickel from the thermal decomposition
of N2H5[M(n)(N2H3COO)n+1]·H2O
and the intermediate M(n)(N2H3COO)n·N2H4
obtained during this decomposition is described and discussed here. In
an inert or reducing atmosphere these compounds decompose to metal particles
of 50 to 70 nm in size. These particles are, in turn, composed of even
smaller particles 5 to 7 nm in size. The advantages, disadvantages and
possible ways of implementing this method for the preparation of nanosize
products are discussed.
