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 ma...

Sodium chlorate crystals were obtained by evaporating drops of saturated aqueous solution in both, ambient conditions, and at a constant temperature in a closed container. The aim of the research was to examine crystallization patterns after slow evaporative drying of sodium chlorate solution drops in a magnetic field. Figure 1a-d. Observed pattern...

Dependence of growth rates of {100} sodium chlorate crystal faces on solution supersaturation in the range of 0.44–1.32% was analyzed. It has been shown that the growth rate dispersion does not have a consequence only in the growth parameter differences predicted by specific crystal growth theory but that individual crystal faces may grow with diff...

This work was conducted to investigate the understanding of the concept of real image observation among students and teachers of physics. We studied the implications of inadequate explanation of the role of the eyes in the observation of the real and virtual images of an object and in understanding the laws of geometrical optics. The eyes have been...

The results of the effect of the growth history on Potassium Dihydrogen Phosphate (KDP) crystals growth mechanism are presented in the paper. Crystals were grown in temperature range of from aqueous solutions, saturated at . Two types of the experiments were performed. In both types, after the nucleation at crystals were grown at the same temperatu...

Difficulties in determining crystal growth mechanism from growth rate versus solution supersaturation dependence are discussed. Obtained results indicate that in the supersaturation range of 0.66 – 1.56%, sodium chlorate crystals grow in accordance with the spiral growth model. It is shown that in the supersaturation range of 0.44 – 1.32% growth me...

Effects of partial dissolution and refaceting on growth rates of sodium chlorate and potassium dihydrogen phosphate (KDP) crystals are presented. Under the same external conditions, crystals of sodium chlorate and KDP exhibit growth rate dispersion (GRD), prior to dissolution and after refaceting. These GRDs were described by multiple normal distri...

Results of investigation of correlation between the {100} face growth rates of small sodium chlorate crystals and the relative solution supersaturation, are presented. Dependence of growth rate of a crystal, R, on relative supersaturation of the solution, σ, is usually described with different equations, according to a different crystal growth mode...

Results of investigation of the influence of partial dissolution on sodium chlorate crystal stabilized growth rates indicate the existence of one dominant maximum in the growth rate distributions in <100> direction .
