HONEYCOMB STRUCTURE, AND METHOD OF PRODUCING HONEYCOMB STRUCTURE
To provide a honeycomb structure that comprises a plurality of parts each having excellent mechanical characteristics and fixing an intersection of ceramic fibers, is not easily broken, and can carry a large amount of a catalyst thanks to its sufficiently high porosity.SOLUTION: The honeycomb structure comprising a ceramic fiber as a main component, at least one species of crystalline inorganic binder selected from silica, alumina, titania, and zirconia, and an amorphous inorganic binder at least containing one species selected from sodium, calcium, boron, potassium, and magnesium, with a plurality of through holes separated by a cell partition-wall and arranged parallel to each other in the longitudinal direction, is characterized in that the porosity of the cell partition-wall is 70% or higher.SELECTED DRAWING: Figure 1
【課題】 セラミックファイバの交差部を固定する部分の機械的特性に優れ、破損しにくく、また、気孔率が充分に高いため、多量の触媒を担持することが可能なハニカム構造体を提供する。【解決手段】 主成分がセラミックファイバと、シリカ、アルミナ、チタニア及びジルコニアから選ばれる１種以上の結晶質無機バインダと、ナトリウム、カルシウム、ホウ素、カリウム及びマグネシウムから選ばれる１種以上を含む非晶質無機バインダと、からなり、複数の貫通孔がセル隔壁を隔てて長手方向に並設されたハニカム構造体であって、前記セル隔壁の気孔率は、７０％以上であることを特徴とするハニカム構造体。【選択図】 図１
