  Phase equilibria in the quaternary system(Li2B4O7+Na2B4O7+Mg2B6O11+H2O)at 303.15K were studied experimentally by using the method of isothermal dissolution equilibrium.The inderite was synthesized by using magnesium sulfate and sodium tetraborate decahydrate reacting in an oil bath at temperature of 40 ℃.
