Stability of Liquid-Lead-Cadmium System

Alloys containing 17,30,38 and 60 atomic percent cadmium respectively were examined in the range 300-600 °c by the Kumar-Samarin technique of centrifuging liquid metals. Whereas smooth concentration gradients were set up in the first three alloys thus indicating stability the 60 at% cadmium alloy decomposed in to two liquids .Regarding the solution as colloidal ,the size of predominantly lead-and cadmium –rich clusters were determined in the first three alloys and found not to change appreciably with temperature.
