To this aim various techniques were used in order to examine the effects of long-term, high-temperature corrosion processes on the selected substrate. It was found that the corrosion products were arranged in a multilayer structure, with LiFeO2, LiCrO2, NiO and FeCr2O4 being the main compounds in the different layers. The composition of the remaining salt after the corrosion tests was also studied, the chromium increase being one of the main points to highlight. The results suggested that longer immersion tests should be carried out to clearly confirm the suitability of HR3C for solar thermal applications.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal articlehttp://dx.doi.org/10.1016/j.solmat.2016.08.014https://www.sciencedirect.com/science/article/pii/S0927024816303063restricted access669.14:620.193Molten saltCarbonateCorrosionHR3CCSPEnergy StorageMateriales3312 Tecnología de Materiales3303 Ingeniería y Tecnología Químicas2213 Termodinámica
