PROCESS FOR PRODUCING CERAMIC HONEYCOMB STRUCTURE

摘要

A process for producing a ceramic honeycomb structure containing aluminum titanate as main crystals, characterized by extruding a plastic green earth consisting of 45:55 to 55:45, in molar ratio, titania powder and alumina powder, or of 100 parts by mass of the sum of such titania powder and alumina powder mixed with 1 to 10 parts by mass of amorphous silica powder so as to form a honeycomb configuration, drying the same and firing the dried extrudate at 1300° to 1700°C.
