<P>PROBLEM TO BE SOLVED: To provide a green compact suitable for manufacturing a honeycomb structural body with high productivity in which a partitioning wall of a sealing part and through-holes is fully sintered. <P>SOLUTION: This green compact 100 is provided with a honeycomb-shape columnar body 70 having a plurality of roughly parallel through-holes 70a, and a sealing material 70b which seals one end of the through-holes 70a. The columnar body 70 has a first end and a second end roughly perpendicular to the through-holes 70a, some of the through-holes 70a are sealed by the sealing material 70b at the first end and are open at the second end, and the other through-holes 70a are sealed by the sealing material 70b at the second end and open at the first end. The sealing material 70b contains ceramic, and the columnar body 70 contains ceramic raw material powder, and the ceramic is aluminum titanate-based ceramic and/or cordierite-based ceramic, and the sealing material shrinkage ratio during sintering is the 80 to 100% of shrinkage rate of the partitioning wall. <P>COPYRIGHT: (C)2012,JPO&INPIT |
