High strength honeycomb structure, method of molding the same, and honeycomb structure converter

A honeycomb structure converter comprising;

• a metallic case, and
• a honeycomb structure canned in the metallic case;
• the honeycomb structure having a number of cells partitioned by partition walls and extending through an axial direction,
• wherein a thickness (TY) of the partition walls whose longitudinal direction is one direction (Y-direction) in a section perpendicular to the axial direction of the honeycomb structure and thickness (TX) of the partition walls whose longitudinal direction is the other direction have a relation of
• 1.10≦TY/TX≦1.33, and
• TX is 10 μm≦TX≦95 μm;
• wherein the honeycomb structure is ceramic and the partition walls whose longitudinal direction is one direction intersect with the partition walls whose longitudinal direction is the other direction.

A method of molding a honeycomb structure, the honeycomb structure having;

• a number of cells partitioned by partition walls and extending through an axial direction,
• wherein a thickness (TY) of the partition walls whose longitudinal direction is one direction (Y-direction) in a section perpendicular to the axial direction of the honeycomb structure and thickness (TX) of the partition walls whose longitudinal direction is the other direction have a relation of
• 1.10TY/TX≦1.33, and
• TX is 10 μm≦TX≦95 μm;
• the method comprising an extrusion molding such that the Y-direction is a direction of gravity;
• wherein the honeycomb structure is ceramic and the partition walls whose longitudinal direction is one direction intersect with the partition walls whose longitudinal direction is the other direction.
