Abstract
Several systems of low melting point mixtures of inorganic salts are disclosed. These compositions can have liquidus temperatures less than 80° C. and thermal stability limits greater than 500° C.
Claims17
A composition comprising:
- a lithium cation, in an amount from about 5 to about 40 mol % based on the cation;
- a potassium cation, in an amount from about 20 to about 70 mol % based on the cation;
- at least two members selected from the group consisting of:
- a sodium cation, in an amount from 0 to about 30 mol % based on the cation,
- a calcium cation, in an amount from 10 to about 25 mol % based on the cation, and
- a cesium cation, in an amount of from 10 to about 40 mol % based on the cation;
- a nitrate anion, in an amount from about 15 to 100 mol % based on the anion;
- and optionally at least one anion selected from the group consisting of
- nitrite, in an amount from 40 to about 90 mol % based on the anion, and
- chloride, in an amount from 0.1 to about 5 mol % based on the anion, wherein when cesium or calcium is not present, the composition comprises nitrite.
