Thermal Characterisation of Binary Sodium/Lithium Nitrate Salts for Latent Heat Storage at Medium Temperatures - dataset

In this
paper, two binary salts, NaNO3 – LiNO3 (46% – 54%) and NaNO3
– LiNO3 (40% – 60%), were investigated to assess their suitability
for medium temperature heat storage. The thermal properties and long term
stability under multiple cycles of each binary salt pair were investigated
using Differential Scanning Calorimetry (DSC). The chemical stability at
elevated temperatures was tested using a Thermogravimetric Analyser (TGA). Both
binary salts analysed have suitable melting temperatures (just under 200 °C)
with relatively high latent heat values (>220 kJ/kg), both exhibiting good
thermal and chemical stability.

在本研究中，对两种二元盐——NaNO3-LiNO3（46%–54%）和NaNO3-LiNO3（40%–60%）——进行了探究，以评估其在中等温度热存储方面的适用性。采用差示扫描量热法（DSC）对每对二元盐的热学性质以及长期稳定性进行了研究，这种稳定性是在多次循环中得以体现的。通过热重分析仪（TGA）对提高温度下的化学稳定性进行了测试。所分析的两种二元盐均具有适宜的熔点（略低于200°C）以及相对较高的潜热值（>220 kJ/kg），均表现出良好的热学和化学稳定性。
