| Abstract: Solubility of the ternary system LiCl-LiNO3-H2O was measured at 273.15 K and 323.15 K by analyzing the equilibrated phase composition. Experimental result shows that there are three solubility branches at 273.15 K, corresponding to the solid phases LiCl·2H2O，LiNO3 and LiNO3·3H2O, respectively, while there are two solubility branches at 323.15 K, corresponding to the solid phase LiCl·H2O and LiNO3. The invariant point compositions are (1) 33.68wt% LiCl, 14.32wt% LiNO3 and (2) 27.70wt% LiCl, 20.60wt% LiNO3 at 273.15 K and (3) 39.07wt% LiCl, 16.89wt% LiNO3 at 323.15 K. Also, the experimental results show that the solid phases in equilibrium with the solution {x(2.8LiCl+LiNO3)-(1-x)H2O} are LiNO3·3H2O or LiNO3 at 273.15 K and LiNO3 at 323.15 K. |
