Abstract
Fusible Sn–Bi eutectic alloy particles were synthesized from bulk Sn–Bi alloy via a high-shear mechanical approach. The morphology, composition, and structure of the as-prepared Sn–Bi alloy particles were characterized by XRD, field-emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, differential scanning calorimetry, thermogravimetry, and Fourier-transform infrared spectroscopy. The particles were found to be spherical and consist of the tetragonal phase of tin as well as the rhombohedral phase of bismuth. In addition, there were large amounts of poly(N-vinylpyrrolidone) coated on the particles.
