• This work aims at studying of an efficient way for synthesizing nano-sized particles of lead-bismuth alloy and illustrating their fabrication mechanisms from SEM morphologies. With highly ordered nano-channels developed on the surfaces of anodic aluminum oxide (AAO) template, the lead-bismuth eutectic (Pb_<45>Bi_<55>) as homogenous melt was cast inside of a sealed tube. It is deduced that the template with its nano-scale asperities works as an ultra phobic surface aids lead-bismuth droplets to be suspended and then solidify to form as nano-spheres. Disordered structure of template introduces more nucleation sites and higher latent heat. In this case, bigger sizes and irregular shapes of nano lead-bismuth are observed inside of the pitting.
