Abstract
The phase formation and reaction kinetics in the TiO2-Cr2O3 system have been studied by x-ray diffraction and electron microscopy. The Cr2O3 solubility in TiO2 has been accurately determined, and the rate parameters of the formation of solid solutions in this system have been evaluated. The results demonstrate that Cr2O3 dissolves in rutile and not in anatase. Cr2O3 markedly reduces the temperature of the anatase-rutile phase transition.
