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: A method of producing fibers includes exposing an inorganic composition to a plasma plume, where the plasma plume has a temperature of at least 1500 °C and a bulk velocity of at least 350 m/s. A system for producing fibers includes a plasma torch to produce the plasma plume and a feeding device to introduce the inorganic composition to the plasma plume.

Abstract: A thermal insulation material includes inorganic fibers and an endothermic material dispersed throughout the inorganic fibers. The endothermic material may be incorporated into the inorganic fibers during a fiber attenuation process. The endothermic material may be particles entangled within a web of the inorganic fibers or may be coated onto surfaces of the inorganic fibers.
