Title:
コージェライト質セラミックハニカム構造触媒用担体及びその製造方法
Document Type and Number:
Japanese Patent JP3587365
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a lightweight honeycomb structure which is light in comparison with other honeycomb structures even when the thickness is the same by increasing porosity in the cell wall and to obtain a catalyst carrier having a ceramic honeycomb structure, which can be rapidly heated and has sufficient mechanical strengths. SOLUTION: The catalyst carrier having the cordierite-based ceramic honeycomb structure is characterized by that the volume of pores having diameters of 0.5 to 2 μm is >=30% of the total pore volume, the volume of pores having diameters of 5 to 10 μm is <=20% of the total pore volume, the volume of pores having diameters of <=10 μm is <=30% of the total pore volume, the porosity is >=35%, the A-axis compressive strength is >=18 MPa and the mass per carrier volume containing cell spaces is <=400 g/l.
