Porous body-coated fiber, porous body-coated particle, and formed article using the same

摘要

Porous body-coated fiber (100F) comprises an inorganic fiber (1F); and a porous body comprising fine inorganic particles associated with one another in ring-shaped or helical manner to form secondary particles (10). The inorganic fiber is coated with the porous body. Independent claims are also included for: (a) a formed article obtained by pressure-forming the porous body-coated fiber; (b) a porous body-coated particle comprising a core particle comprising a second inorganic compound, and a porous body comprising fine particles of a first inorganic compound associated with one another in ring-shaped or helical manner to form secondary particles; (c) a formed article precursor comprising fiber material(s) from an inorganic fiber, and the inventive porous body-coated fiber, and the porous body-coated particle.
