36 kinds of mixed salts made of KCl, Na 2 CO 3 and K 2 CO 3 were prepared in this paper. The melting point and solidification point of the sample were studied by DSC, and the stability of the selected samples is also tested. The experimental results show that the smaller component of KCl, the smaller melting point of molten salt. The melting point of the samples which melted together was 570 -580°C, and the freezing point is mainly between 550 and 570 C. The test ratio of the samples were

The sample has a low melting point at 568.9°C and a low freezing point at 545.3°C, which can effectively avoid the blockage of piping system. The research results in this paper will provide reference and basis for the application of ternary mixed molten salt in solar energy field.
