HEAT TRANSFER FLUIDS AND HEAT STORAGE FLUIDS FOR EXTREMELY HIGH TEMPERATURES BASED ON POLYSULFIDES

摘要

The invention relates to a composition for transporting and storing heat energy, comprising alkali polysulfides of the form (Me1(1-x)Me2x)2 Sz, where Me1 and Me2 are selected from the group of alkali metals made of lithium, sodium, potassium, rubidium, and cesium, and Me1 is not the same as Me2, and x = 0 to 1 and z = 2.3 to 3.5.
