· JVASP-10755· CaCr4O8

CaCr₄O₈ is a calcium chromium oxide ceramic compound belonging to the chromite family of oxides. This material is primarily used in high-temperature refractory applications and specialized industrial processes where chromium-bearing ceramics provide chemical stability and thermal resistance. It is notable in refractory brick manufacturing and metallurgical furnace linings due to its ability to withstand corrosive molten slag and extreme thermal cycling, making it preferable to alumina or magnesia-only refractories in environments requiring chromium oxide's distinctive chemical durability.
