Abstract
The titanium-niobium oxide compositional system shows potential for application
in a variety of technologically important material systems. However, this system is not
well understood. In this study, a titanium niobium mixed-phase system was prepared via
the sol gel method and characterized as a function of heat treatment temperature.
Differential thermal analysis, thermogravimetric analysis and high temperature X-ray
diffraction (HTXRD) were used to characterize the mixed-phase system. The purpose of
the current investigation is to gain insight into the phases and their structural
characteristics present in the phase-mixed system. To do so, the system was studied
using three approaches. First, the influence of the titanium to niobium metal ion ratio on
the phase assemblage was examined. Next, the influence of composition on
crystallization temperature was determined. Finally, the influence of composition and
heat treatment temperature on phase transformation temperature and assemblage was
investigated. This approach suggests that the precursor materials and heat treatment
regiment affects the phase assemblage.
