Abstract (en)
[origin: WO2014026915A1] Disclosed is a method for maintaining or extending the long-term operating temperature range of a heat transfer medium and/or heat storage medium containing a nitrate salt composition selected from among the group consisting of alkali metal nitrate and alkaline earth metal nitrate and, optionally, alkali metal nitrite and alkaline earth metal nitrite. Said method is characterized in that the entire nitrate salt composition or a portion thereof is brought in contact with an additive composed of a combination of elemental oxygen and nitrogen oxides.
