STABILITY OF LIQUID PB-CD SYSTEMS

Alloys containing 17, 30, 38 and 60 at. % cadmium were examined in the range 300 to 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 into two liquids. Regarding the solution as colloidal, the sizes of predominantly lead- and cadmium-rich clusters were determined in the first three alloys and found not to change appreciably with temperature. © 1969 Chapman and Hall.
