ABSTRACT:
A low-melting point, heat transfer fluid comprising a mixture of LiNO3, NaNO3, KNO3, NaNO2and KNO2salts where the Li, Na and K cations are present in amounts of about 20-33.5 mol % Li, about 18.6-40 mol % Na, and about 40-50.3 mol % K and where the nitrate and nitrite anions are present in amounts of about 36-50 mol % NO3, and about 50-62.5 mol % NO2. These compositions can have liquidus temperatures between 70° C. and 80° C. for some compositions.
