Fe3+ and Ce3+ acting as competitive impurities in the crystallization process of potassium hydrogen phthalate from solutions

Remarkable enhancement in optical and thermal properties of sodium hydrogen phthalate hemihydrate crystals due to Fe3+ doping

“…on potassium hydrogen phthalate crystals have been investigated in detail. These impurities affect the growth kinetics, morphology, quality and various other properties of phthalate crystals [9,[14][15][16]. In the present case Fe was used as a dopant in SP crystals.…”

Rapid growth of KDP crystal with new additive

“…It can effectively suppress chemical activity of the metal ions present in the KDP solutions due to the formation of complexes with the functional groups of EDTA by its chelating action. The metastable zone width was found to be enhanced in the case of EDTA-added solution when compared to the pure system [3]. The growth rate of KDP is reported to increase 6-8 times when grown from EDTA-added solution as compared to pure solution [4].…”

Enhancement of stability of growth, structural and NLO properties of KDP crystals due to additive along with seed rotation

“…Strong changes in growth kinetics and crystal morphology may be caused by even very low additive concentrations, 0.1-1 ppm [11,12]. The growth promoting effect of KDP crystals is observed in the presence of organic additives [13,14] as well as inorganic additives [15,16]. This contribution can be attributed to the adsorption of additives on the surface of the nuclei resulting in change of the nuclei surface free energy and nucleation mechanism.…”
