Abstract: | The growth rate of {100}-faces of KBr crystals has been found to decrease in the presence of aliphatic carbon acids according to the dependence earlier deduced by one of the authors (Bliznakov 1954; 1958). The passivating effect is greater with acids having a greater number of CH2-groups. The isotherms of passivation have been obtained at various temperatures. On the basis of experimental data the heat of adsorption of the impurities (acids) at the active growth centers of {100}-faces of KBr crystals have been calculated. The passivating effect is greater with acids which are adsorbed more strongly. |
