Physical Properties:

Chromium dioxide [12018-01-8], chromium(IV)oxide, CrO2, is a ferromagnetic material with a specific saturation magnetization Ms/ of 132 A m2 kg1 at 0 K, corresponding to the spin of two unpaired electrons per Cr4+ ion. TheMs/n value of CrO2 at room temperature is ca. 100 A m2 kg1; CrO2 magnetic pigments reach values of 77–92 A m2 kg1. The material crystallizes with a tetragonal rutile lattice in the form of small needles, which have the desired magnetic shape anisotropy. The morphology of the particles can be varied with several dopants, particularly antimony and tellurium. The coercive field strength can be controlled between ca. 30 and 75 kA m1 (in addition to shape) by doping with transition metal ions, which modify the magneto-crystalline anisotropy of the material; the Fe3+ ion being industrially important.

Density:

4.85 g/mL at 25 °C(lit.)

Melting Point:

>375 °C (dec.)(lit.)

Boiling Point:

decomposes to Cr2O3℃ [KIR78]

Water Solubility:

insoluble H2O, soluble acids giving Cr+++and dichromate [KIR78]

Storage Conditions:

Experimental Properties:

Black semiconducting material; acicular crystals having strong magnetic properties|At room temperature and normal pressure chromium dioxide is metastable; when heated to temperatures above 350 °C, it decomposes into chromium(III) oxide and oxygen. Chromium dioxide has an oxidizing action on reactive organic compounds.
