Li₂CO₃-K₂CO₃ and its nanofluids have been widely studied for thermal energy storage media in concentrated solar power due to their largely enhanced specific heat capacity values. On the other hand, Li₂CO₃-Na₂CO₃ and its nanofluids have not been explored although Li₂CO₃-Na₂CO₃ has a larger specific heat capacity than Li₂CO₃-K₂CO₃. Therefore, in this study, we synthesized Li₂CO₃-Na₂CO₃ and Li₂CO₃-K₂CO₃ pure salt eutectic mixtures and their nanofluids. These mixtures were then tested for three distinct thermophysical properties, specific heat capacity, viscosity, and thermal stability. The obtained experimental results of all four systems were evaluated for use as thermal energy storage media in concentrated solar power.

Li ₂ CO ₃ -K ₂ CO ₃及其纳米流体因其大大增强的比热容值而被广泛研究用于聚光太阳能中的热能存储介质。另一方面，尽管Li ₂ CO ₃ -Na ₂ CO ₃具有比Li ₂ CO ₃ -K ₂ CO ₃更大的比热容，但尚未探索Li ₂ CO ₃ -Na ₂ CO ₃及其纳米流体。因此，在本研究中，我们合成了 Li ₂ CO ₃-Na ₂ CO ₃和Li ₂ CO ₃ -K ₂ CO ₃纯盐共晶混合物及其纳米流体。然后测试这些混合物的三种不同的热物理性质、比热容、粘度和热稳定性。对所有四个系统获得的实验结果进行了评估，以用作聚光太阳能中的热能存储介质。
