Abstract

A method for the preparation of amorphous Ni powder with particle size of about 10 nm is reported. The sonolysis was performed on neat Ni(CO)4 and on its solution in decane. The nickel nanoparticles were subjected to scanning and transmission electron microscopy, differential scanning calorimetry, thermogravimetric analysis, X-ray diffraction and SQUID magnetization measurements. These measurements confirm the amorphous state of the particles.
