Abstract: 36 kinds of mixed salts made of KCl,Na2CO3 and K2CO3 were prepared.The melting point and solidification point of the samples were studied by DSC,and the stability of the selected samples were also tested.The results showed 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℃,and the freezing point was mainly between 550 and 570℃.The test ratio of the samples were selected from experiments was 2∶3∶5(KCl∶Na2CO3∶K2CO3).The samples had a low melting point at 568.9℃ and a low freezing point at 545.3℃,which can effectively avoid the blockage of piping system.The research results will provide reference and basis for the application of ternary mixed molten salt in solar energy field.
