Abstract
A porous cordierite substrate and a method of forming a porous cordierite substrate including providing a fiber that includes at least one cordierite precursor material and providing at least one organic binder material. The fiber and the organic binder material are mixed with a fluid. The mix of fiber, organic binder material and fluid is extruded into a green substrate. The green substrate is fired to enable the formation of bonds between the fibers and to form a porous cordierite fiber substrate.
Claims33
A method of forming a porous cordierite substrate comprising:
- providing a fiber including at least one cordierite precursor material;
- providing at least one organic binder material;
- mixing the fiber and the at least one organic binder material with a fluid;
- extruding the mixed fiber, at least one organic binder material and fluid into a green substrate;
- and
- firing the green substrate to enable formation of bonds between fibers and to form a porous cordierite fiber substrate.
A porous cordierite fiber substrate comprising:
- an extruded substrate including an extrusion composition of a fluid, at least one organic binder material and fiber including at least one cordierite precursor material, the extruded substrate being sintered to consolidate regions between the fibers and to form a fired substrate including a cordierite composition.
A porous cordierite substrate comprising:
- a non-cordierite extruded substrate including one of biosoluble silica-magnesia fiber or magnesia alumina silicate fiberglass, at least one organic binder material and a fluid, the non-cordierite extruded substrate being sintered to enable formation of bonds between the fibers and to form a substrate including a cordierite composition.
