摘要The solubility and ultra solubility of boric acid (H3BO3) in solutions with different concentrations of MgCl2 and NaCl were determined by using laser detection technique. In addition, the metastable zones of H3BO3 in these solutions were obtained. Furthermore, the nuclear progression m of H3BO3 was calculated. Our experimental results showed that the stable area of H3BO3 was narrow at high temperature, and wide at low temperature. Compared to the solubility of H3BO3 only in water, the solubility of H3BO3 decreased with increasing amount of MgCl2 and NaCl in water and was more affected by MgCl2 than by NaCl. The metastable zone of H3BO3 first became narrower and then wider with increasing concentrations of MgCl2 and NaCl. The metastable zone of H3BO3 in MgCl2 and NaCl solutions was narrower than in the H3BO3-H2O system. The effect of MgCl2 on apparent nucleus progression of H3BO3 was much more than that of NaCl. The crystal grew better in medium concentration of MgCl2 and low concentration of NaCl because of the smaller nuclear progression. Therefore, crystal with greater granularity can be obtained in such buffer condition.
