Cr2O3 is a green powder. Cr2O3 can be used as pigment.
Example Reactions:
• (NH4)2Cr2O7 = Cr2O3 + N2 + 4H2O
• Cr2O3 + 3KNO3 + 2K2CO3 = 3KNO2 + 2K2CrO4 + 2CO2
• Cr2O3 + 3CO2 = Cr2(CO3)3
• Cr2O3 + 2Al = Al2O3 + 2Cr
• 3Mg + Cr2O3 = 3MgO + 2Cr
• Cr2O3 + 3H2 = 2Cr + 3H2O
• Cr2O3 + 3H2S = Cr2S3 + 3H2O
• 2Cr(OH)3 = Cr2O3 + 3H2O
• Cr2O3 + 6HCl = 2CrCl3 + 3H2O
• Cr2O3 + 3KNO3 + 4KOH = 2K2CrO4 + 3KNO2 + 2H2O
