1. 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.
