Non isothermal kinetic study of the aluminium titanate formation in alumina-titania mixtures

open access: yesCerâmica, 2014
Aluminum titanate (Al2TiO5) is a high refractoriness material with excellent thermal shock resistance. Hence it is suitable for several applications at elevated temperatures where insulation and thermal shock resistance are required.
