) Abstract: The thermal stability of the eutectic Na2CO3-NaCl molten salt was investigated from the melting point to 1 000 ℃. The mass loss at high temperatures, the cycle performance, the component, structure and morphology after the heat treatment were evaluated. The results show that the volatility of eutectic composition is between pure NaCl and pure Na2CO3. The volatility of molten salt is sharply......
