| Abstract: | The result of study on the ternary system K~+,Mg~(2+)/B_4O~(2-)_7-H_2O at 25℃ has been reported. The system is of a simple eutectic type. The solubility isotherm of the system consistes of two branches and has two crystallization areas,corresponding to MgB_4O_7·9H_2O and K_2B_4O_7·4H_2O. The composition of the eutectic point is 13.96 weight percent of K_2B_4O_7 and 0.53 weight percent of MgB_4O_7,respectively. |
