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.
