First claim
Opening claim text (preview).
What is claimed is: 1. A honeycomb structure comprising a pillar-shaped honeycomb structure body having partition walls defining a plurality of cells which become through channels for a fluid and extend from a first end face to a second end face, wherein the partition walls comprise a porous body having refractory aggregates and a bonding material which bonds the refractory aggregates to each other, the bonding material includes metal silicon and an oxide material, porosity of the porous body constituting the partition walls is 25% or more and 55% or less, a ratio of the mass of the bonding material to the mass of the whole porous body is 30 mass % or more and 50 mass % or less, a ratio of the mass of the oxide material to the mass of the bonding material is 30 mass % or more and 80 mass % or less, a ratio of the mass of the oxide material to the mass of the whole porous body is 26 mass % or more and 40 mass % or less, and a thermal conductivity at 800° C. is 5 W/(m·K) or more and 28 W/(m·K) or less. 2. The honeycomb structure according to claim 1 , wherein the porosity of the porous body is 25% or more and 32% or less. 3. The honeycomb structure according to claim 2 , wherein the oxide material includes, as a main component, an oxide including at least one metal element selected from the group consisting of Al, Si and Mg or a mixture including two or more types of the oxides. 4. The honeycomb structure according to claim 3 , wherein a heat capacity at 800° C. is 2.5 J/(cc·K) or more. 5. The honeycomb structure according to claim 2 , wherein a heat capacity at 800° C. is 2.5 J/(cc·K) or more. 6. The honeycomb structure according to claim 1 , wherein the oxide material includes, as a main component, an oxide including at least one metal element selected from the group consisting of Al, Si and Mg or a mixture including two or more types of the oxides. 7. The honeycomb structure according to claim 6 , wherein a heat capacity at 800° C. is 2.5 J/(cc·K) or more. 8. The honeycomb structure according to claim 1 , wherein a heat capacity at 800° C. is 2.5 J/(cc·K) or more.
