Abstract
The production method of the present invention is a method for producing porous aluminum magnesium titanate by forming a mixture containing Al source powder, Mg source powder, Ti source powder and Si source powder as well as a pore-forming agent to obtain a molded body; presintering the obtained molded body; and then sintering the presintered molded body, wherein the content of the pore-forming agent to a total of 100 parts by mass for the Al source powder, Mg source powder, Ti source powder and Si source powder is 5 to 30 parts by mass, the melting point of the Si source powder is 600 to 1300° C., when the elemental composition ratio of Al, Mg, Ti and Si in the mixture is represented by compositional formula (1):AlMgTiO+aAlO+bSiO  (1),x satisfies 0.05≦x≦0.15, a satisfies 0≦a≦0.1 and b satisfies 0.05≦b≦0.15, and the presintered molded body is sintered at 1300 to 1560° C.
