Copper chromite Usage And Synthesis

Chemical Properties

copper chromite is a black, tetragonal powder that is insoluble in water. It is prepared by the heating to 400°C of copper(II) chromate(VI).

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.

Preparation

Copper(II) chromite is obtained by heating copper chromate, CuCrO4 at 400°C. The Adkin catalyst, a mixture of copper oxide and copper chromite, is prepared by mixing aqueous solutions of copper nitrate, sodium dichromate and ammonium hydroxide; the orange precipitate of copper ammonium chromate formed is dried and then heated below 400°C.
