Abstract: A heat transfer or storage medium containing a nitrate salt composition including at least one alkali metal nitrate and optionally alkaline earth metal nitrate; and, at least one alkali metal nitrite and optionally alkaline earth metal nitrite in an amount of 1.1 to 15.0 mol %. The molar amount of the alkali metal nitrite and optionally alkaline earth metal nitrite for a desired temperature is calculated by x nitrite = K 6 ⁡ ( T ) K 6 ⁡ ( T ) + P O ⁢ ⁢ 2 Xnitrite is the mole fraction of nitrite, K6(T) is the temperature-dependent equilibrium constant of the reaction nitrate ⇄nitrite+½ oxygen (NO3−⇄ NO2−+½ O2), pO2 is the oxygen partial pressure and T is the temperature of the nitrate salt composition.
