低熔点多元混合熔盐的制备及其性能研究
Preparation and properties on multicomponent molten salts with low melting point
摘要
Abstract
To obtain newly multi-component molten salts with lower melting point used as thermal storage media and heat transfer fluid in concentrating solar power, the reciprocal quinary molten mixture was prepared by adding NaCl into the ternary eutectic molten mixture of LiNO3-KNO3-Ca (NO3)2. And then, differential scanning calorimeter (DSC) and thermogravimetric analysis (TG) and other thermal test were carried out. The results showed that the melting point of the reciprocal quinary molten mixture is 109.3℃with the latent heat is 48.6 J/g, which is lower 7.9℃than that of the ternary eutectic molten mixture. The thermal stability temperature is 500℃, which is higher 50℃ than that of the ternary eutectic molten mixture. And the density of the reciprocal quinary molten mixture is 1.7~1.9 g/cm3 with the temperature range 180~500℃.关键词
