Abstract: | A Contribution on Ternary Oxides of the AMO4-Type (A = Ti3+, Cr3+; M = Nb5+, Ta5+ ) CrNbO4, CrTaO4, TiNbO4, and TiTaO4 were prepared by CO2-laser technique. X-ray single crystal investigations show a random distribution of the metal ions in Rutil type structure, space group D–P42/mnm. Calculations of the free energy of reaction between Ti2O3 and Nb2O5 show higher stability of TiO2 beside NbO2. In TiNbO4 both metals exhibit the oxidation state +4. |
