Abstract
Molten salt eutectics have potential applications in Thermal Energy Storage (TES) systems as Phase Change Materials (PCMs), however eutectic salts with melting temperatures above 400°C are highly corrosive under air atmospheres. A method for testing under inert atmosphere is presented and results from testing under isothermal and thermal cycling conditions for two salts (NaCl/Na2CO3 and NaCl/Na2SO4) with melting temperatures of around 630°C are discussed. Chromium oxides were present at the salt/metal interface whilst iron and nickel remained in metal phase.
