Synthesis of nanocrystalline Ni-Fe alloy powders by spray pyrolysis

Nanocrystalline 70 wt.% Ni-30 wt.% Fe alloy powders were synthesized by spray pyrolysis from a solution of nickelcene (C2H5)(2)Ni and ferrocene (C2N5)(2)Fe dissolved in 2-methoxyethanol. The alloy powder consisted of <10 nm and 70 to 80 nm particles. Thermodynamic analysis is shown to be a useful tool for gaining insight into the thermochemistry of the spray pyrolysis process.
