Abstract
A method for storing an inorganic salt, wherein the inorganic salt has a long service life, and the stability of a salt melt made of the inorganic salt is increased. This is achieved in that the inorganic salt is provided in a liquid state, wherein the inorganic salt comprises anions which decompose when heat is supplied, thereby forming at least one gaseous decomposition product, and the pressure of the gas atmosphere is set such that the gas atmosphere is in chemical equilibrium with the inorganic salt in the liquid state.
Claims12
A method for storing an inorganic salt, the method comprising:
- providing an inorganic salt in liquid state, comprising anions which on supply of heat decompose to form at least one gaseous disintegration product;
- and
- setting a pressure of a gas atmosphere, the gas atmosphere being in a chemical equilibrium with the inorganic salt in liquid state, wherein
- the gas atmosphere comprises at least one nitrogen oxide,
- an oxide ion fraction of the inorganic salt accommodated in a fluidtight manner is less than 0.02 mol %, and
- an optional gas region is a spatial region of a receiving container in which the gas atmosphere is disposed in a filled state of the receiving container.
