More Information
Summary:Filtration articles herein exhibit excellent filtration efficiency and pressure drop before and after water durability testing. The articles comprise: a honeycomb filter body; inorganic deposits disposed within the honeycomb filter body at a loading of less than or equal to 20 grams of the inorganic deposits per liter of the honeycomb filter body. The inorganic deposits are comprised of refractory inorganic nanoparticles bound by a high temperature binder comprising one or more inorganic components. At least a portion of the inorganic deposits form a porous inorganic network over portions of inlet walls of the honeycomb filter body.
