We have investigated the electronic and structural properties of chromia (Cr2O3), a typical Mott-Hubbard insulator. We considered the T=0 K antiferromagnetic insulating ground state and the paramagnetic insulating state above the Néel temperature (TN). Our treatment of the latter resembles in principle a virtual crystal model of the random spins insulator and describes reasonably well the compressive behavior of chromia above and the structural anomalies across TN.
