Phase diagrams of magnesium nitrate-based molten salts were investigated by DSC measurement, including binary systems Mg(NO3)2-KNO3, Mg(NO3)2-LiNO3, and a portion of ternary system Mg(NO3)2-LiNO3-NaNO3. The results show that the melting point of the compound 2KNO3·Mg(NO3)2 is found at 223.95 °C, and this compound does not have a solid state transition. Mg(NO3)2-KNO3 system has two eutectic transitions, one at 177.07 ± 3 °C and the other at 192.51 ± 1 °C for mixtures with 43.00 ± 1 wt % KNO3 and 70.50 ± 1 wt % KNO3, respectively; Mg(NO3)2-LiNO3 system is a simple eutectic system with one eutectic occurring at 209.23 ± 1 °C for a mixture with 58.00 ± 1 wt % LiNO3. Mg(NO3)2-LiNO3-NaNO3 ternary system has three eutectic curves and one ternary eutectic point at 132.39 ± 2 °C for a mixture with 47.50 ± 2 wt % Mg(NO3)2, 13.50 ± 2 wt % LiNO3, and 39.00 ± 2 wt % NaNO3.
