HONEYCOMB STRUCTURE AND EXHAUST GAS PURIFYING DEVICE

摘要

This honeycomb structure has a honeycomb unit that contains ß zeolite, a phosphate zeolite, and an inorganic binder and that has a plurality of through-holes that are provided in parallel in the lengthwise direction separated by partitions. The ß zeolite has an average particle size of secondary particles of 0.5-5 µm inclusive, the phosphate zeolite has an average particle size of primary particles of 0.5-5 µm inclusive, and the ratio of the mass of the phosphate zeolite to the total mass of the ß zeolite and the phosphate zeolite is 5-35% inclusive.
