· AlCrO3

AlCrO3 (aluminum chromium oxide) is a ceramic compound belonging to the spinel or mixed oxide family, combining aluminum and chromium oxides into a single-phase material. It is primarily investigated for high-temperature structural applications and wear-resistant coatings where chemical stability and hardness are critical; industrial adoption remains limited, with most use in research settings for thermal barrier systems, cutting tools, and refractory applications where superior oxidation resistance and thermal stability compared to single-oxide alternatives are advantageous.
