Abstract |
The effect of magnetic treatment of KDP and ADP crystals and solutions on their equilibrium temperature has been revealed and studied. The change in the temperature reaches a maximum immediately after the magnetization. Then, the effect decreases monotonically, and the equilibrium temperature approaches its equilibrium value for 5 h. It has been found that the observed decrease in the solubility depends on the impurity concentration, and it is maximum in magnetically treated KDP crystals with a chromium impurity; then, it decreases in the series: KDP crystal, KDP-ADP crystals in a KDP-ADP solution, KDP crystal in KDP-ADP solution, and KDP solution. For all five systems under study, the relaxation times have been determined. It has been revealed that the effect rapidly increases and reaches saturation at B = 0.02 T. The energy effects in the crystals and solutions have been estimated. |
