Study on Modification of Hitec Molten Salt and its Properties Tests

In this paper, additive A and additive B were added into Hitec molten salts in order to optimize the properties of the molten salt. The melting point, latent heat of phase transformation, specific heat capacity, thermal gravity, and thermal stability of the modified Hitec molten salt was characterized. The results showed that compare to Hitec molten salt the modified Hitec molten salt showed low melting point, proper latent heat of phase transformation, greater heat of fusion, wide using temperature range and other advantages. The modified molten salt had good thermal properties and thermal stability. This modified Hitec molten salt has good application prospect in the aspect of high temperature heat storage/transfer.
