A method for producing a sintered product comprising an aluminum magnesium titanate represented by the empirical formula: MgxAl2(1-x)Ti(1+x)O 5, wherein x is 0.1 <= x < 1, as a basic component, characterized in that it comprises providing a first mixture containing a Mg-containing compound, an Al-containing compound and a Ti-containing compound in a ratio between Mg, Al and Ti being the same as the ratio between the metals in the above empirical formula, preparing a raw material mixture containing 100 parts by weight of the first mixture and 1 to 10 parts by weight of an alkali feldspar represented by the empirical formula: (NayK1-y)AlSi3O8, wherein y is 0 <= y <= 1, and sintering a formed product from the raw material mixture. The method allows the production of an aluminum magnesium titanate sintered product which retains low thermal expansion property inherent in an aluminum magnesium titanate sintered product and can be continuously used with stability even at a high temperature, and further has good mechanical strength.
