Abstract:
A nitrate salt composition comprising A) an alkali metal nitrate and optionally an alkali metal nitrite in a total amount in the range from 90 to 99.84% by weight and B)an alkali metal compound selected from the group B1) alkali metal oxide, B2) alkali metal carbonate, B3) alkali metal compound which decomposes into alkali metal oxide or alkali metal carbonate in the temperature range from 250° C. to 600° C., B4) alkali metal hydroxide MetOH, in which Met is lithium, sodium, potassium, rubidium, cesium, B5) alkali metal peroxide Met2O2, in which Met is lithium, sodium, potassium, rubidium, cesium, and B6) alkali metal superoxide MetO2, in which Met is sodium, potassium, rubidium, cesium, in a total amount in the range from 0.16 to 10% by weight, in each case based on the nitrate salt composition.
