Document Type and Number:
WIPO Patent Application WO/2007/015495
Kind Code:
A1
Abstract:
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.
