Useful:

• Physical properties: Grayish-black tetragonal crystals; density 5.4 g/cm3. When heated to elevated temperatures (above 900°C) copper(II) chromite decomposes to cupric chromate(II), CuCrO2 and chromium (VI) oxide, CrO3. Copper(II) chromite is insoluble in water and dilute acids.
• uses: Copper chromite is used as a hydrogenation catalyst.
