“…KDP and Rochelle salt crystals that did not grow or that stopped growing were likely missing for the same reason or because of the relatively high supersaturation. The appearance of crystals that did not grow and crystals that stopped growing under supersaturated solutions was noticed earlier for both KDP ,, and Rochelle salt ,,, crystals.…”

Results of investigations of the changes in growth rate inherent to crystals (i.e., independent of macroscopic external conditions) during a 15-h growth period are presented. The results of the investigations regarding the time evolution of the growth rate dispersion are also presented. The majority of the investigations were carried out with sodium chlorate crystals, and several experiments were carried out with potassium dihydrogen phosphate (KDP) and Rochelle salt crystals. It was found that, for the majority of the crystals, the main changes in growth rate occurred in the initial growth stage, which extended to for up 4 h. These growth rates probably slowly decrease toward the end of the growth run. Some of the very high initial growth rates that decreased during the initial growth period were followed by relatively high intermediate growth rates for the next few hours and then subsequently decreased. The growth rates for the majority of crystals probably gradually decreased after 15 h of growth. The results obtained show that these changes, which have not previously been taken into account, should be included in the interpretation of growth rate changes affected by various parameters (supersaturation, temperature, fields, stress, impurities, etc.). The obtained results could improve the current crystal growth theories, which are based on the design of specific growth conditions that result in a target product.

“…4 The displacement rate of the (100) faces of ammonium dihydrogen phosphate crystals was lower when a magnetic field of 0.17 T was applied. 5 Also, a magnetic field of 0.22 T decreases the growth rates in the [010] direction of most Rochelle salt crystals studied 6 and of most MnCl 2 ·4H 2 O crystals in the direction perpendicular to the plane (100). 7 A magnetic field of 0.18 T also decreases the growth rates of calcite.…”

Influence of a Static Magnetic Field on the ⟨100⟩ Growth Rates of Sodium Chlorate Crystals from Aqueous Solution

The results of the study of the influence of a static magnetic field of 55 ± 3 mT on the growth rates of diamagnetic sodium chlorate crystals in the direction ⟨100⟩ will be presented. Two groups of experiments were performed in the same solution supersaturation range of 0.89−1.78%, the first in zero field conditions, and the second in an applied magnetic field. The results show that crystals nucleated and grown in a static magnetic field have higher mean growth rates in the ⟨100⟩ direction than crystals in a zero field. Also, X-ray analyses suggest that crystals nucleated and grown in a magnetic field may have a higher lattice constant. Possible mechanisms and possible reasons for these phenomena are discussed.

“…A magnetic field is one of factors relevant to crystallization alongside with concentration of input reagents temperature acidity of the reaction environment, and availability of complexing agents etc. In literature [1][2][3][4] there are results presented, which indicate an enormously growing number of nuclei when crystallizing inorganic salts of water solutions. Its number increases almost proportionally to the field intensity.…”

“…Its number increases almost proportionally to the field intensity. Furthermore, magnetic treatment changes some physical properties of systems (electrical conductivity, density, surface tension, dielectric permeability, magnetic susceptibility, and viscosity) [2,4]. Indeed, the residual effect of the magnetic field decreases constantly.…”
