(57) [Problem] To improve the mechanical strength while maintaining the original properties of an aluminum titanate sintered body having a small coefficient of thermal expansion and good corrosion resistance, and to be used stably even at high temperatures. Provided is a possible aluminum titanate-based sintered body. A the TiO 2 and Al 2 O 3 the former: the latter (weight ratio) = 40: 60 to 60: a mixture 10 containing a ratio of 40 Chemical formula: (Na x K 1-x ) AlSi 3 based on 0 parts by weight Alkali feldspar represented by O 8 (0 ≦ x ≦ 1) is 1 to 15 A method for producing an aluminum titanate-based sintered body, characterized in that a molded body formed from a raw material mixture obtained by mixing parts by weight is fired at 1400 to 1700 ° C. |
