Abstract

A fine powder of β-nickel aluminide NiAl is obtained by reaction of [Ni(cod)₂] (cod = cycloocta-1,5-diene) with AlEt₃ in toluene at room temperature and under a H₂ pressure of 5-10 MPa and subsequent distillation of the solvent, subsequent hydrogenation (0.1-5 MPa), and annealing (200°C) [Eq. (a)]. This novel wet chemistry synthesis of aluminides may be transferred to Ni₃Al (α-nickel aluminide) and ternary aluminide powders such as GaNiAl, FeNiAl, and CeNiAl.
