The reduction of aluminium titanate (Al2TiO5) heated at various temperature in the range of 1000∼1500°C in the reducing atmosphere containing hydrogene has been studied by the methods of X-ray analysis, differential thermal analysis and thermogravimetric analysis.
The aluminium titanate was prepared by heating Al2O3-TiO2 compacts in air at 1550°C for three hours.
As shown in Fig. 3, the X-ray patterns of Al2TiO5 heated at different temperatures under the reducing atmosphere containing hydrogene have shown an observable shift in the (33.0) line and the evidence of α-Al2O3.
From the relation between the d value or density of the product formed by the reduction of Al2TiO5 and the extent x of solid solution, it is seen that the product is a solid solution such as {(1-x)Al2O3+xTi2O3}·TiO2.
