| dc.description.abstract | Titania/alumina ceramic powders (TiO2/ Al2O3/ TiO2˙Al2O3) was studied by combustion synthesis as volatilized precursors in premixed CH4+O2+N2 flame. The experiment was used 0.32% titanium precursor (TTIP) under different oxidizer composition conditions. When the molar ratio of oxygen to nitrogen (O2/N2) was 40/60, the result showed that the anatase content was 97.7 wt%. Oppositely, the anatase phase transform to the rutile phase gradually when the molar ratio of oxygen to nitrogen was reducing. Beside the effect of the temperature, the results also showed that oxygen content was the key to control crystalline phase changes. In similar way, the crystalline phase changes were found in the order of Al2O3-γ→δ→θ→ | en |
