Partial Coordination Numbers in Pb-Bi Molten Alloys

摘要

The study of the partial coordination numbers for the Pb-Bi liquid alloy showed an increase in the partial coordination number for the Pb-Pb species at 0.75 atomic fraction Bi. This anomaly suggests that the Pb atoms manifest some level of homocoordination within the neighbourhood of that concentration. It also provides an explanation for the observed change in the total coordination number of the liquid alloy at high Bi concentration.
