The influence of 1 wt.% Pb, Cu, Ge and Si on the transformation kinetics of the β-Sn→α-Sn transformation in high-purity powder mixtures was examined using synchrotron powder X-ray diffraction. Pb and Cu were found to be effective in suppressing α-tin growth. Ge and Si inhibited the β→α transformation. The kinetics of the transformation are largely determined by the nucleation of α-Sn.
