HONEYCOMB FILTER AND MANUFACTURING METHOD OF HONEYCOMB FILTER
To provide a honeycomb filter hardly reduced in PM catching performance.SOLUTION: A honeycomb filter comprises: an exhaust gas introduction cell which includes a porous cell partition wall defining and forming a plurality of cells to be a flow passage of exhaust gas and of which the end at the side of an exhaust gas inlet is opened and the end at the side of an exhaust gas outlet is plugged; and an exhaust gas exhaustion cell of which the end at the side of the exhaust gas outlet is opened and the end at the side of the exhaust gas inlet is plugged. In the honeycomb filter, the cell partition wall is composed of an SiC porous body, and an average particle size of SiC particles constituting the SiC porous body ranges from 10 to 50 μm. SiC fine particles having an average particle size ranging from 1 to 5 μm are sintered and deposited on a surface of the cell partition wall at the side of the exhaust gas introduction cell.SELECTED DRAWING: Figure 5
【課題】 ＰＭ捕集性能が低下しにくいハニカムフィルタを提供する。【解決手段】 排ガスの流路となる複数のセルを区画形成する多孔質のセル隔壁を備え、排ガス入口側の端部が開口され、かつ、排ガス出口側の端部が目封止された排ガス導入セルと、排ガス出口側の端部が開口され、かつ、排ガス入口側の端部が目封止された排ガス排出セルと、を備えてなるハニカムフィルタであり、上記セル隔壁はＳｉＣ多孔体からなり、上記ＳｉＣ多孔体を構成するＳｉＣ粒子の平均粒子径は１０～５０μｍであり、上記セル隔壁の上記排ガス導入セル側の表面には、平均粒子径が１～５μｍのＳｉＣ微粒子が焼結付着している、ことを特徴とするハニカムフィルタ。【選択図】 図５
