Honeycomb ceramics used as catalys carrier for purifying exhaust gases of the automobiles necessitate high thermal shock resistance quality and special low coefficient of thermal expansion. In this paper, after the analysing of the average - coefficient of thermal expansion and micro - coefficient of thermal expansion of cordierite ceramics, the thermal dilative characteristic of cordierite honeycomb was studied.
