Microfine composite titania-alumina powders were prepared using mixed alkoxide or mixed chloride starting materials. Amorphous coprecipitated precursors formed on hydrolysis were subjected to various heat treatments: calcination, hydrothermal processing or heating as an aqueous slurry under reflux conditions. The effects of preparation conditions on the polymorphous form and microstructure of these biphasic powders were studied. Samples were characterised by X-ray powder diffraction and-electron microscopy, and preliminary Al-27 solid state magic angle spinning (MAS) NMR data is also reported. The hydrolysis of TiCl4 and mixed TiCl4/AlCl3 was shown to yield crystalline. rutile at unexpectedly low temperatures.. (C) 2002 Elsevier Science Ltd. All rights reserved.
