POROUS MATERIAL, MANUFACTURING METHOD OF THE SAME, AND HONEYCOMB STRUCTURE
There is disclosed a porous material suitably having a broad range of a firing temperature and having excellent thermal resistance and excellent thermal shock resistance. The porous material contains aggregates, and a bonding material which bonds the aggregates to one another in a state where pores are formed among the aggregates, the bonding material contains crystalline cordierite, the bonding material further contains a rare earth element or a zirconium element, and a ratio of a mass of the bonding material to a total mass of the aggregates and the bonding material is from 12 to 45 mass%. The bonding material preferably contains, in the whole bonding material, 8.0 to 15.0 mass% of MgO, 30.0 to 60.0 mass% of Al 2 O 3 , 30.0 to 55.0 mass% of SiO 2 , and 1.5 to 10.0 mass% of a rare earth oxide or zirconium oxide.
