FAST FIRING METHOD FOR CERAMICS
PROBLEM TO BE SOLVED: To provide a firing cycle with increased heating rates, particularly a firing cycle with increased heating rates up to 600°C, that does not cause cracking in a ceramic body.SOLUTION: A method for firing a green honeycomb ceramic body in a kiln may include heating the green honeycomb ceramic body in four stages: the first stage from room temperature to a first temperature at a first heating rate that is greater than or equal to about 75°C/hr; the second stage from the first temperature to a second temperature at a second heating rate that is less than or equal to the first heating rate; the third stage that may include heating the green honeycomb ceramic body from the second temperature to a hold temperature at a third heating rate that is less than or equal to the first heating rate; and the fourth stage that may include holding the green honeycomb ceramic body at the hold temperature to remove residual carbon.SELECTED DRAWING: Figure 1
【課題】セラミック体にひび割れを生じさせない、加熱速度を向上させた焼成サイクル、特には６００℃までの加熱速度を向上させた焼成サイクルの提供。【解決手段】キルン中の未焼結ハニカムセラミック体を焼成するための方法は四つの段階で未焼結ハニカムセラミック体を加熱することを含んでいてもよい。第一の段階は、室温から第一の温度まで、約７５℃／時間以上の第一の加熱速度で、行う。第二の段階は、第一の温度から第二の温度まで、第一の加熱速度以下である第二の加熱速度で、行う。第三の段階は、第二の温度から保持温度まで、第一の加熱速度以下である第三の加熱速度で、未焼結ハニカムセラミック体を加熱することを含んでいてもよい。第四の段階は、残留炭素を除去するために未焼結ハニカムセラミック体を保持温度で保持することを含んでいてもよい。【選択図】図１
