Popis In our work we developed synthetic strategies for preparation of alloy nanoparticles of Bi, Ni and Sn in which we used a reduction route. NaBH4 and BH3.H2NtBu were used to reduce particular metal salts to obtain nanoparticles of zero-valent metal alloys. Polyvinylpyrrolidone or 1,10-phenanthroline were used as surfactants to stabilize their surface. Prepared NPs, their phases and phase transformations were studied by Powder X-Ray Diffraction (PXRD), Transmission and Scanning Electron Microscopy (TEM, SEM/EDS) (Fig. 2) and Differential Scanning Calorimetry (DSC). The results were compared with both bulk and nano phase diagrams and were in good agreement with theoretical predictions.
