| Abstract: | The heats of dilution and heat capacities of eutonic point solution system Li_2B_4O_7—Li_2SO_4—LiCl—H_2O and subsystems Li_2B_4O_7—Li_2SO_4—H_2O and Li_2B_4O_7—LiCl—H_2O were measured to cover ionic strength range from 19 to 0. 1 at 298. 15K. The data of the heat of dilution were extrapolated to infinte dilution by use of the Debye-Htickel liminting law to obtain relative apparent molal enthalpies. |

| Keywords: | boron-lithium systems heat of dilution heat capacity apparent molal enthalpy |
