It is prepared by reacting titanium dioxide with titanium metal at 1600 °C. Ti2O3 has the Al2O3, corundum structure. It is reactive with oxidising acids. At around 200 °C there is a transition from semiconducting to metallic conducting. Natural titanium(III) oxide is known as the extremely rare mineral tistarite.Mindat, http://www.mindat.org/min-38695.html
