CERAMIC FILTER AND MANUFACTURING METHOD THEREOF
To provide a ceramic filter and its manufacturing method capable of restraining a pressure drop increase quantity.SOLUTION: A ceramic filter 90 of the present invention has an outer peripheral wall 70, and a porous partition wall arranged on the inside of the outer peripheral wall 70 and dividing and forming a plurality of cells forming a flow passage penetrating from an inflow surface 91 (one end surface) up to a flow out surface 92 (another end surface). The cells include: a plurality of first cells opening on the end surface side of the inflow surface 91 (the one end surface) and having a mesh sealing part on the flow out surface 92 (the other end surface) side; and a plurality of second cells opening on the flow out surface 92 (the other end surface) side and having a mesh sealing part on the inflow surface 91 (the one end surface) side. An effective porosity of the partition wall is 0.1 or more.SELECTED DRAWING: Figure 1
【課題】圧損上昇量を抑えることができるセラミックスフィルター及びその製造方法を提供する。【解決手段】本発明によるセラミックスフィルター９０は、外周壁７０と、外周壁７０の内側に配設され、流入面９１（一方の端面）から流出面９２（他方の端面）まで貫通する流路を形成する複数のセルを区画形成する多孔質の隔壁とを備え、セルは、流入面９１（一方の端面）の端面側が開口して流出面９２（他方の端面）側に目封止部を有する複数の第１セルと、流出面９２（他方の端面）側が開口して流入面９１（一方の端面）側に目封止部を有する複数の第２セルとを含み、隔壁の有効気孔率が０．１以上である。【選択図】図１
