Chromium is also being looked at for resistive thermal storage, due to the stability properties you mentioned. Doped chromia (Cr2O3) bricks act as both thermal storage elements and resistive heating elements up to 1800 C. https://electrifiedthermal.com/ https://electrifiedthermal.com/ https://dspace.mit.edu/handle/1721.1/130800 https://dspace.mit.edu/handle/1721.1/130800
