摘要The solubility and ultra solubility of boric acid in aqueous were measured in the presence of different concentrations of KCl and NH4Cl from 0 degrees C to 25 degrees C. The metastable zones and the crystal nucleation orders of H3BO3 were calculated. Effects and action mechanism of KCl and NH4Cl on metastable zone property of H3BO3 were studied. The result shows that the existence of KCl makes the metastable ione of H3BO3 move to higher temperature by increasing solubility of H3BO3. According to the adsorption effect, NH4Cl makes metastable zone of H3BO3 move to lower temperature. Concentration variation of KCl and NH4Cl in evaporation of Nayishan oilfield brine is one of the reasons that boron crystallizes dispersedly.
