A honeycomb structural body and a diesel-particulate filter

Title:

A honeycomb structural body and a diesel-particulate filter

Document Type and Number:

Japanese Patent JP5934220

Kind Code:

B2

Abstract:

A honeycomb structure includes honeycomb units which contain silicoaluminophosphate particles and an inorganic binder and are provided with a plurality of cells that extend in the longitudinal direction from a first end surface to a second end surface of the honeycomb structure and are partitioned by cell walls, in which Si/(Al+P) of the silicoaluminophosphate particles is in a range of 0.16 to 0.33 by molar ratio, a thickness of the cell wall is in a range of 0.10 mm to 0.25 mm, a cell density of the cells is in a range of 93 cells/cm 2 to 155 cells/cm 2 , and a ratio R/L of a diameter R of the honeycomb structure to a total length L of the honeycomb structure is 1.0 or more.
