Applications of Chromium Aluminum Oxide
1. High-Temperature Coatings
Used in thermal barrier coatings (TBCs) and protective layers for aerospace and turbine components due to outstanding oxidation and erosion resistance.
2. Pigments and Surface Finishes
Cr–Al–O systems yield stable green and olive hues, ideal for ceramic pigments, architectural coatings, and high-temperature paints that retain color over decades.
3. Catalysts and Catalyst Supports
Cr–Al oxides are utilized in oxidation and dehydrogenation reactions, offering high surface stability and mechanical strength for petrochemical and environmental catalysts.
4. Refractory and Structural Ceramics
As a component in high-temperature refractories, chromium aluminum oxide enhances thermal shock resistance and chemical durability under oxidizing atmospheres.
5. Wear-Resistant and Optical Layers
Thin Cr–Al–O coatings improve hardness, abrasion resistance, and optical reflectivity in precision optics and industrial tooling.
