| Abstract: | In this paper,the activities(amount of iodine and specific surface) of MgO were determined. The activety MgO in relative with calcinating temperature was presented. The influences of the MgO activity,the calcinating temperature, the dissolution temperature and the concentration of MgCl 2 on the solubility of MgO were discussed.Also covered was the relation between various B 2O 3 to MgO ratios in the MgCl 2 solution and the solubility augmentation of MgO in the supersaturated magnesium borate solution. |
