This study was performed to stabilize the physical properties of Sodium Carbonate Decahydrate that was selected as a highly concentrative thermal energy storage medium. The addition of ARS(additives to prevent supercooling) showed to prevent the supercooling of Na$_{2}$CO$_{3}$.10H$_{2}$O, and the supercooling was decreased below $1.5^{circ}C$ with ARS of 3 wt% and the addition of PSC(phase separation controller) of 1.5 wt% controlled the phase separation of Na$_{2}$CO$_{3}$ .10H$_{2}$O with the phase change cycles increased from 0 to 1,500, the phase change temperature and the latent heat has changed in the range of 30$pm$1.$0^{circ}C$ and 54$pm$2.0Kcal.kg$^{-1}$ respectively.
