POROUS MATERIAL, HONEYCOMB STRUCTURE, AND METHOD OF MANUFACTURING POROUS MATERIAL |
摘要 |
There is disclosed a porous material which has an improved thermal shock resistance. The porous material contains aggregates and a composite binder. The composite binder includes glass as a binder and mullite particles as reinforcing particles, and the mullite particles are dispersed in the glass. The aggregates are connected to each other by the composite binder in a state where pores are formed in the porous material. Preferably, a lower limit of a percentage of a content of the composite binder to a total mass of the aggregates and composite binder is 12 mass %, and an upper limit of the percentage of the content of the composite binder to the total mass of the aggregates and composite binder is 50 mass %. Preferably, the glass contains MgO, Al2O3 and SiO2 and further contains at least one selected from a group consisting of Na2O, K2O and CaO. |

1. A porous material comprising:
aggregates; and a composite binder which includes glass as a binder and mullite particles as reinforcing particles such that the mullite particles are dispersed in the glass, wherein the aggregates are bound together by the composite binder in a state where pores are formed in the porous material. |
