Abstract
The present invention provides a process for preparing an aluminum-titanate-based sintered body comprising the step of firing, at 1250 to 1700° C., a formed product prepared from a raw material mixture containing 100 parts by weight of a mixture of TiOand AlOin a weight ratio of TiO:AlO=40:60 to 60:40, and 1 to 15 parts by weight of an alkali feldspar represented by the formula:(NaK)AlSiOwherein 0≦x≦1. According to the process of the present invention, it is possible to obtain an aluminum-titanate-based sintered body in which inherent properties of an aluminum titanate, i.e., a low coefficient of thermal expansion and high corrosion resistance are maintained, the mechanical strength thereof is improved, and which can be stably used even under high temperature conditions.
