ABSTRACT:
A process for firing ceramic honeycomb structural bodies at a certain temperature in a given atmosphere is disclosed. The ceramic honeycomb structural bodies are fired, while a gas having a temperature equal to that of an atomsphere surrounding the exterior of the ceramic honeycomb structural bodies is forcedly passed through holes of the ceramic honeycomb structural bodies. By this firing process, a pore-forming agent and/or a shaping aid admixed in the ceramic honeycomb structural bodies can effectively be burnt away and the entire honeycomb structural bodies can uniformly be fired. Thus, fired ceramic honeycomb structural body having desired dimensions can be obtained in a shortened firing time.
