Abstract
A method for producing a ceramic honeycomb structure comprising aluminum titanate as a main crystal, comprising the steps of mixing titania powder, alumina powder and amorphous silica powder, the molar ratio of the titania powder to the alumina powder being 45:55 to 55:45, the amount of the amorphous silica powder being 1-10 parts by mass per 100 parts by mass of the total of the titania powder and the alumina powder, to produce a moldable material; extruding said moldable material in a honeycomb shape; drying it; and then sintering it at 1300-1700° C.
