ABSTRACT OF THE DISCLOSURE A multicellular monolithic ceramic body having many gas passages partitioned by thin walls is made of aluminum titanate as a major constituent and has a thermal expansion coefficient of 1000°C of less than 0.15% and a compressive strength as zero of an open frontal area higher than 350 kg/cm2 as the properties in the direction along the gas passages and a porosity of more than 35%. The honeycomb has characteristics of high heat resistance, high porosity, high compressive strength and a low thermal expansion coefficient which is suitable for cleaning automotive emissions.
