1.用等温法测定在30℃时K2CO3-K2SO4-H2O,K2B4O7-K2CO3-H2O和K2B4O7-K2SO4-H2O三个三元体系的溶解度等温线.在上述体系中存在K2CO3·3/2H2O,K2SO4和K2B4O7·4H2O固相.2.研究在30℃时K2CO3-K2SO4-K2B4O7-H2O四元体系的溶解度等温线.相图中只有K2SO4和K2B4O7·4H2O两个有效相区.

By means of isothermal method,solubility isotherms have been studied for ternary systems K2CO3-K2SO4-H2O,K2B4O7-K2CO3-H2O and K2B4O7-K2SO4-H2O at 30℃.The solid phases which occur are K2SO4,K2CO3·3/2H2O and K2B4O7·4H2O Solubility isotherms of quaternary systems.K2CO3-K2SO4-K2B4O7-H2O have been investigated at 30℃.There are two effective regions of the single solid phases K2SO4 and K2B4O7·4H2O in the orthogonal projection diagram.
