Abstract

Solid solutions of Cr3+ ions in TiO2 have been prepared by impregnating commercial TiO2 with CrO3(aq) and annealing in O2 at 770 K. X-Ray diffraction data show the absence of a segregated Cr2O3 phase. The magnetic and spectroscopic properties have also been investigated.

Abstract

Твердые растворы ионов Cr3+ в TiO2 были приготовлены импрегнированием торгового TiO2 с CrO3(водн.) и аннелированием в O2 при 770 К. Рентгенодиффракционные данные свидетельствуют об отсутствии сегрегативной фазы Cr2O3. Были исследованы также их магнитные и спектроскопические свойства.
