Molten salt LiNO3-NaNO3-KNO3 has been investigated as heat transfer and thermal storage media for its low melting point good performance. In this paper, nanofluids were synthesized by dispersing MgO nanoparticles into LiNO3-NaNO3-KNO3, the effects of on properties studied with different sizes (20–100 nm) mass percent concentrations (0.5–2.0 wt.%). The addition had little effect temperature, led...
