The BaO–Fe2O3–TiO2ternary phase diagram has been investigated at 1250–1270°C in air. X-ray diffraction studies of approximately 150 polycrystalline specimens at room temperature confirmed the existence of sixteen ternary compounds. Two of these compounds, BaFe4Ti2O11and Ba12Fe28Ti15O84, ...
X-ray powder diffraction data and refined unit cell parameters for three compounds found during experimental determination of the BaO:Fe2O3:TiO2 phase diagram are reported here. All three phases crystallize in space group C2/m (No. 12). Ba2Fe2Ti4O13 ("2:1:4") is isostructural with ...
while the representative curve is shown inFig. 5a. During the cathodic scan process, each of the TiO2@Fe2O3arrays exhibits three reduction peaks around 1.75 V, 1.4 V and 0.8 V. The first peak is ascribed to the phase transition from tetragonal ...
