Abstract
This investigation reports the structure and stability of liquid lead-antimony alloys determined with the help of the Kumar-Samarin technique of centrifuging liquid metals. It shows that liquid lead-antimony alloys in the composition ranges 0 to 35 and 65 to 100 at. % antimony are stable and can be regarded as a colloidal dispersion of lead- and antimony-rich clusters in monatomic matrices; the cluster size is minimum at the eutectic composition. The paper suggests that solutions in the intermediate composition range corresponding to the inflection in the liquidus curve are incipiently immiscible and shows that they can be separated into conjugate phases.
