Abstrakt: Fine nanoparticles of Ni were formed in molten LiCl-KCl-CsCl electrolyte under 1 atm of Ar atmosphere by plasma-induced cathodic discharge electrolysis using the rotating disk anode-type electrolytic cell. The relations between the size of the formed nanoparticles and the electrolysis conditions, such as the rotation speed of the disk and the electrolysis current value, were investigated. Ni nanoparticles with diameters of less than 10 nm were obtained at a rotation speed higher than 2000 rpm. The size of the obtained Ni nanoparticles depends on the rotation speed of the disk but not on the electrolysis current value. Based on the obtained results, the particle growth process just under the discharge is discussed. [ABSTRACT FROM AUTHOR]
