Phase formation and stability of polycrystalline NazGa4+zTi1-zO8, (z～0.7)

摘要：

The formation and stability of polycrystalline NaxGa4+xTi1-xO8, (x～0.7) was examined. High temperature x-ray diffraction (HTXRD) showed that NaxGa4+xTi1-xO8, (x～0.7), begins to form from component oxides and carbonates at ～950℃ and shows complete reaction within 24 h while being held at 1050℃. The desired Na0.7Ga4.7Ti0.3O8 phase remains only nominally phase pure with residual gallium oxide identifiable. Further heating of the reacted material results in the decomposition of the material beginning at ～1200℃ in which Ga2O3 and other intermediate phases are seen in the diffraction pattern.
