Abstract

Incorporating solar energy in the housing sector requires adequate materials for energy storage. Eutectic mixtures of hydrated inorganic salts are a good alternative. This study uses the BET model to represent the solid-liquid equilibrium of two ternary systems and to predict eutectic points of quaternary systems. The results suggest that the LiNO3+NaNO3+Ca(NO3)2+H2O system has great potential for use as an energy storage material.
