|Title:||Experimental Investigation Of A Multi-stage Purification Process For Metals|
|Abstract:||An experimental investigation is presented of a multi-stage purification process which utilizes fractional solidification in a way related to that employed in zone melting. The process, for which the term cascade purification has been suggested, is shown to be technically viable. The validity of a previous theoretical analysis of the expected solute redistribution has been broadly confirmed via radiatracer detection of tin and zinc in an aluminium base. Factors controlling the purification efficiency are outline, with particular reference to minimizing the solute-enriched boundary layer ahead of the growth front through control of the melt convection. © 1981.|
