The formation of com- pounds TaVO5 and VTa9O25 in the V2O5–Ta2O5 binary system was verified. Tetragonal VTa9O25-base solid solutions of the general formula Ta5 + 4xV5 – 4xO25 (x = 0.25–1) and TaVO5-base solid solutions of the general formula TaxMo1 – xV2 – xO8 – 3x (x = 0.625–1) were found to form. Subsolidus phase equilibria in the V2O5–Ta2O5–MoO3 were determined Полный текст |
