混合熔融盐低温共熔区的密度计算
Densities of component salts in low-temperature eutectic region
摘要
Abstract
By establishing a theoretical model, the density of the molten salt is calculated and compared with the experimental data. The error analysis shows that the quadratic polynomial model is the best calculation method. Low-temperature eutectic region (LTER) of mixed molten salts is defined as the temperature range between the melting temperature of mixed salts and the highest melting temperature of component salts. The molten salt is a solid-liquid coexistence state in LTER, and the thermal properties cannot be directly measured. It must be obtained by a combination of theoretical research and experimental verification. Using the quadratic polynomial model, the density of the mixed molten salts in LTER is calculated by extrapolation method. The density in the whole temperature range is obtained with little error, which proves that the theoretical calculation method is feasible. In order to reduce the error in the molten salt density, the experimental data are from the same literature or the same research group.关键词
