<P>PROBLEM TO BE SOLVED: To provide a method for firing green body which achieves the desired high porosity in aluminum titanate articles while doing so with reduced firing cycle length and/or without producing cracked parts and/or complicating the drying process. <P>SOLUTION: The method for firing green body comprises heating the green body containing aluminum titanate forming inorganic batch materials and a pore former in a furnace to a top temperature within a hold temperature range having an upper limit of below 1,550°C and a lower limit of above 1,350°C to form a main phase of aluminum titanate, and fast cooling from the lower limit at an average cooling rate greater than 100°C/hour to below 1,000°C, wherein decomposition of the main phase of aluminum titanate is minimized. <P>COPYRIGHT: (C)2010,JPO&INPIT |
