A computational thermal analysis for the zone-refining processes of Cd and Te

Effect of applied electric current on impurity transport in zone refining

“…All other physical properties related to Te, Cd, quartz, heaters, insulator, and the geometrical and operating parameters can be found in Tables 1 and 2 of Ref. [22].…”

“…Extensive theoretical, numerical, and experimental efforts have been made to achieve this goal [14][15][16][17][18][19][20][21][22][23][24][25][26]. These efforts have focused mainly on enhancing mass transport of impurities in the vicinity of the solidification interface, and on increasing the travel rate of the molten zone.…”

“…[22], a threeheater system developed in Ref. [26] was modelled to simulate the industrial zone refining process of Te and Cd.…”

Application of an Artificial Intelligence Technique to Improve Purification in the Zone Refining Process

“…The solute distribution during solidification depends essentially on a number of factors such as the growth rate, and heat and mass transfer parameters. [11][12][13][14][15] A detailed computational thermal analysis has been used for a better understanding of the mechanisms of the zone refining process, permitting parametric operational aspects to be included in the analysis. 14 An electric current can also be applied to influence mass transport by moving the species of the liquid mixture in the direction of the applied electric current.…”

Experimental impurity segregation and numerical analysis based on variable solute distribution coefficients during multi-pass zone refining of aluminum

“…Three-dimensional simulations of a zone melting process, with a focus on fluid flow in the molten zone have also been developed by Lan and collaborators [6]. Liu et al [7] and Dost et al [8] have carried out three-dimensional simulations for a zonerefining process of Cd and Te, taking into account the Marangoni convection effect.…”
