Abstract
Tialite, beta-Al2TiO5, a low expansion material, has been synthesised by the combustion of corresponding metal nitrates and carbohydrazide ( CH) or urea redox mixtures at 500-degrees-C. As prepared powders conta ined tialite, rutile, and corundum in the mole ratios of 50:25:25 (CH) and 20:40:40 (urea). The combustion derived powders, when calcined 30 min at 1300-degrees-C, gave single phase beta-tialite having a surfac e area of 20-25 m2 g-1 and a particle size of 0.79-1.03 mum.
