      The primary temperatures of NaCl-KCl-NaF molten salt system with different proportion were measured by differential thermal analysis. Significant regression equation between primary crystallization temperature of this molten salt system and component contents was established by regression analysis applying symmetry-simplex design. The results show that the system of 0.45NaCl-0.45KCl-0.10NaF (mole fraction) has lowest primary crystallization temperature.
