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)₂Ni and ferrocene (C₂N₅)₂Fe 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.
