Abstract：
Presents the preparation of the molten salt with 54% KNO3 and 46% NaNO3 and the process of the experiment. Studies the influence of heating rate and integrating range on the melting point. The results show that the melting point of the material is 220.55 ℃ with a good stability. The effects of the heating rate and integrating range on the melting point can almost be ignored, but the integrating range has a larger influence on the latent heat of the molten salt.
