ABSTRACT:
The present invention provides a process for preparing a sintered body comprising as a basic component aluminum magnesium titanate represented by the composition formula: MgxAl2(1−x)Ti(1+x)O5wherein the value of x is 0.1≦x<1. The process comprises a step of sintering a formed product from a raw material mixture comprising 100 parts by weight, calculated on an oxide basis, of a mixture comprising a Mg-containing compound, an Al-containing compound and a Ti-containing compound at the same metal component ratio as the metal component ratio of Mg, Al and Ti in the above composition formula, and 1–10 parts by weight of an alkali feldspar represented by the composition formula: (NayK1−y)AlSi3O8wherein the value of y is 0≦y≦1.According to the process of the present invention, a sintered body of aluminum magnesium titanate having stability in continuous use at high temperatures and excellent mechanical strength, while maintaining inherently low thermal expansibility of a sintered body of aluminum magnesium titanate, can be obtained.
