Abstract: An inorganic fiber containing a fiberization product of a compound comprising at least one alkaline earth silicate, at least one compound containing an element from group VII and/or IX of the periodic table, and optionally alumina and/or boria. The inclusion of a suitable amount of at least one compound containing an element from group VII and/or IX of the periodic table of elements to an alkaline-earth silicate inorganic fiber reduces fiber shrinkage, decreases biopersistence in physiological solutions, and enhances mechanical strength beyond that of alkaline earth silicate fibers without the presence of the at least one compound containing an element from group VII and/or IX. Also provided are methods of preparing the inorganic fiber and of thermally insulating articles using thermal insulation prepared from the inorganic fibers.

Abstract: Fire protective compositions include colloidal silica solids, clay, a low biopersistence fiber or refractory ceramic fiber, water, and optionally a chelating agent. Methods of using the fire protective compositions include providing a polymeric foam substrate, applying the fire protective composition on the polymeric foam substrate, and allowing the fire protective composition to dry.

Abstract: An inorganic fiber containing silica, alumina, one or more alkali metal oxides, and one or more of alkaline earth metal oxides, transition metal oxides, or lanthanide series metal oxides. The inorganic fiber exhibits good thermal performance at use temperatures of 1260° C. and greater, retains mechanical integrity after exposure to the use temperatures, is free of crystalline silica upon devitrification, is alkali flux resistant, exhibits low bio-persistence in an acidic medium, and exhibits low dissolution in a neutral medium. Also provided are thermal insulation products incorporating the inorganic fibers, a method for preparing the inorganic fiber and a method of thermally insulating articles using thermal insulation prepared from the inorganic fibers.

Abstract: A composite fiber includes a porous silicon phase including elemental silicon and a porous carbon phase including elemental carbon. The silicon phase and the carbon phase form an intertwined network structure in the composite fiber such that each of the silicon phase and the carbon phase is interconnected and continuous throughout the composite fiber. The silicon phase and the carbon phase together constitute at least 50 wt % of the composite fiber.
