新型低熔点硝酸盐熔盐的热力学性质
Thermal properties of a low-melting-point nitrate molten salt system
摘要
Abstract
The thermal properties of a Ca(NO3)2- KNO3( 0.47∶0.53) based nitrate molten salt with an additive (0.1% to 15%) was prepared, characterized and cost-analyzed. Such a system has a low melting point, a high specific heat capacity and a high thermal decomposition temperature. It was shown that the new formulation had a melting point of 120.1 ℃ with a latent heat of fusion of 76.37 J·g-1, a decomposition temperature of 588 ℃, and an average specific heat of 1.598 J·(g·K)-1, illustrating an enhanced performance than traditional solar salt and Hitec formulations. The results also suggested a cost of RMB 108 yuan per kW·h.关键词
