1 grams Cr2O3 is equal to 0.006579362907131 mole. Note that rounding errors may occur, so always check the results. Al 2 O 3 and Cr 2 O 3 are the highly stable sesquioxides having an isostructural crystal structure (hexagonal system of space group R-3c) and ionic radii close to those of Al 3+ and Cr 3+. At high temperatures, they form complete substitutional solid solutions over the entire composition range without the formation of any eutectic,.
