CaCr2O4

Calcium chromite (CaCr₂O₄) is a ceramic oxide compound belonging to the chromite family, characterized by a crystalline spinel-related structure. It is primarily used in high-temperature refractory applications and specialized industrial ceramics where thermal stability and chemical resistance are critical. This material is valued in steelmaking furnaces, cement kilns, and other extreme-temperature environments where its resistance to slag corrosion and thermal shock makes it preferable to less stable alternatives, though it remains less common than traditional chromite refractories in mainstream applications.
