PROBLEM TO BE SOLVED: To provide a method of manufacturing slurry for denitration catalysts which does not become high in viscosity with time without using any additives such as an ammonia aqueous solution, and a waste gas denitration device including a honeycomb structure supporting a stable support amount of a denitration catalyst using the slurry for denitration catalyst manufactured by the method.SOLUTION: In a method for manufacturing slurry for denitration catalysts that includes a first process of suspending titania particles in silica sol, a second process of adding powder of ammonium metavanadate to the slurry obtained in the first process, and a third process of further adding a solution or powder of ammonium metatungstate to the slurry obtained in the second process, water is added to the slurry containing the silica sold and titania particles obtained in the first process after irradiation with an ultrasonic wave before the second process, or water is added to the slurry containing the silica sol, the titania particles and the powder of ammonium metavanadate obtained in the second process after irradiation with an ultrasonic wave before the third process. |
