Abstract

Cold trap apparatus for the purification of liquid metal such as sodium comprises a cooled vessel (20) within which a number of concentric cylinders (23) are located such that the liquid metal flow takes place downwardly in the gap between the vessel (20) and the outermost cylinder (23) and upwardly along the gaps between the cylinders (23). The cylinders (23) present extended surfaces across which the liquid metal flows with deposition of solute (24) along such surfaces. The surfaces of the cylinders (23) may be of a roughened nature with respect to the liquid metal flow, e.g. they may be covered with a single layer mesh (21).
