<p>A method for producing an aluminum titanate sintered object, characterized in that a formed product prepared from a law material mixture which comprises 100 parts by weight of a mixture containing TiO2 and Al2O3 in a proportion (former : latter, weight ratio) of 40 : 60 to 60 : 40 and 1 to 15 parts by weight of an alkali feldspar represented by the chemical formula: (NaxK1-x)AlSi3O8 (0 = x = 1) is fired at 1250 to 1700 ° The method allows the production of an aluminum titanate sintered object which retains a small coefficient of thermal expansion inherent in an aluminum titanate sintered object and at the same time has improved mechanical properties and can be used stably at a high temperature.</p> |
