SILICOALUMINOPHOSPHATE PARTICLES, HONEYCOMB STRUCTURE, METHOD FOR MANUFACTURING THE SAME AND EXHAUST GAS PURIFYING APPARATUS
Objects of the invention are to provide silicoaluminophosphate particles that have excellent NOx purification performance and can suppress water adsorption-caused contraction and water desorption-caused expansion and to provide a honeycomb structure that has excellent NOx purification performance and can suppress the breakage of the honeycomb unit due to the adsorption or desorption of water, a method for manufacturing the honeycomb structure, and an exhaust gas purifying apparatus including the honeycomb structure. The silicoaluminophosphate particles of the invention have a metallic oxide attached to silicoaluminophosphate particles with a ratio of an amount of Si to a sum of amounts of Al and P in a range of 0.16 to 0.33, in which a specific surface area is in a range of 250 m 2 /g to 450 m 2 /g, and an external surface area is in a range of 10 m 2 /g to 35 m 2 /g.
