METHOD FOR MANUFACTURING POROUS CERAMIC ARTICLES WITH REDUCED SHRINKAGE

PROBLEM TO BE SOLVED: To provide a method for manufacturing porous ceramic articles, in which the method includes a step of forming a plurality of extruded green bodies from a ceramic precursor batch composition.SOLUTION: A method includes a step of forming a plurality of extruded green bodies from a ceramic precursor batch composition. The method also includes the steps of: calcining the extruded green bodies in a tunnel kiln (10) to produce porous ceramic articles; periodically determining a shrinkage characteristic of at least one sample passing through the tunnel kiln; and adjusting a top soak temperature in the kiln if the shrinkage characteristic is outside of a predetermined range.SELECTED DRAWING: Figure 1 【課題】セラミック前駆体バッチ組成から複数個の押出未焼成体を形成する工程を含む、多孔質セラミック品を製造する方法の提供。【解決手段】セラミック前駆体バッチ組成から複数個の押出未焼成体を形成する工程を含む。トンネルキルン１０内で押出未焼成体を焼成して、多孔質セラミック品を作製する工程、トンネルキルンを通過している少なくとも１つのサンプルの収縮特性を定期的に決定する工程及び、収縮特性が所定の範囲内になければ、キルン内の最高均熱温度を調節する工程も含む多孔質セラミック品の製造方法。【選択図】図１
