Abstract
Nano-sized particles of Sn-Sb alloy powders were synthesized by three kinds
of reductive precipitation methods: rapid mixing, slow (solution) titration and
slow titration with microwave assistance. The structure and morphology of
synthesized Sn-Sb alloy powders were evaluated by X-ray diffraction (XRD),
scanning electron microscope (SEM), and transmission electron microscope
(TEM). Slow, rapid mixed Sn-Sb alloy powders exhibit trace of parent
materials and relatively large particle size (average) of 100-250 nm. In
contrast, the microwave assisted Sn-Sb shows almost negligible influence
from the parent material and a narrow size distribution (40-70nm). The
particle size characterization through SEM, TEM and Dynamic Light
Scattering in dispersed fluid agreed well with each other.
