HONEYCOMB STRUCTURE, METHOD FOR PRODUCING SAME, EXHAUST GAS PURIFICATION DEVICE, AND SILICOALUMINOPHOSPHATE PARTICLES

摘要

A honeycomb structure of the invention includes a honeycomb unit provided with a plurality of through holes arrayed in a longitudinal direction with a partition wall therebetween, in which the honeycomb unit is produced by extruding and firing raw material paste containing silicoaluminophosphate particles and an inorganic binder, and the silicoaluminophosphate particles have a specific surface area in a range of 200 m 2 /g to 400 m 2 /g, and an acid point of 1.2 mmol/g or more.
