Effect of impurity adsorption on the growth of Rochelle salt crystals

Growth of sodium chlorate crystals in the presence of potassium sulphate

“…The impact of impurities, or additives, on the crystallization in aqueous solutions has been intensively studied both in theoretical [1][2][3][4][5] and experimental [6][7][8][9][10][11][12][13][14][15] work, as some compounds added even in a very small amount can essentially modify growth rate, properties and quality of growing crystals. Impurity is adsorbed from the bulk solution to the surface of the crystal; therefore, it can decelerate its growth either by blocking kinks on the face or edges on the steps [16,17], or by formation of an impurity film on the face [18,19].…”
