Abstract
A honeycomb structure has a longitudinal axis, a ceramic structure extending along the longitudinal axis and having a large number of cells partitioned by a partition, and a coating layer arranged on an outer surface of the ceramic structure. The main component of the coating layer is molten inorganic oxide.
Claims19
A honeycomb structure having a longitudinal axis, comprising:
- a ceramic structure extending along the longitudinal axis and having a large number of cells partitioned by a partition;
- and
- a coating layer arranged on an outer surface of the ceramic structure, wherein the coating layer contains molten inorganic oxide as a main component.
The honeycomb structure according to claim 3, wherein the molten inorganic oxide comprises one selected from the group consisting of molten silica, molten alumina, molten titania, and molten zirconia.
A method for manufacturing a honeycomb structure, the method comprising the steps configured to:
- prepare a coating agent containing a molten inorganic oxide, a binder, and a solvent;
- apply the coating agent to an outer surface of a ceramic structure including a longitudinal axis and a ceramic structure extending along the longitudinal axis and having a large number of cells partitioned by a partition;
- and
- form a coating layer by hardening the coating agent;
- wherein the coating agent contains the molten inorganic oxide as a main component.
