Effect of added polymer traces in crystal growth: electrochemical simulation

Résumé

Crystals grown in convective media often show defects related to solution flux. Traces of polyethylene oxide (PEO) added to potash alum crystal growth solution slightly reduce the growth rates but significantly improve the quality of the crystal. In order to interpret this action, an electrochemical simulation of mass transfer during growth was attempted. It has been shown that the PEO additive does not act as drag reducer but is adsorbed at the interface, forming a porous filter through which chemical species diffuse.
