Agile Thermal Management STT-RX: Themophysical Properties of Lithium Nitrate Trihydrate from - 20 degrees C to 80 degrees C (Preprint)
Abstract
Lithium nitrate trihydrate is of interest as a thermal energy storage material, due to its large specific and volumetric heats of fusion and its low melting temperature. Here, we report the thermophysical properties of solid and liquid lithium nitrate trihydrate at temperatures between -20 deg C and 80 deg C and compare this compound to water and octadecane, two other potential thermal energy storage materials. Furthermore, we examine the lithium nitrate-water phase diagram and accurately determine the enthalpies of fusion and melting points for lithium nitrate trihydrate (DeltaH(fus = 264 plus or minus 2 J.g(-1), Tau(m) = 28.3 deg C).
