Inorganic fiber

摘要

An inorganic fiber containing silica and magnesia as the major fiber components and which further includes an intended iron oxide additive to improve the dimensional stability of the fiber. The inorganic fiber exhibits good thermal insulation performance at 1400° C. and greater, retains mechanical integrity after exposure to the use temperature, and which remains non-durable in physiological fluids. Also provided are thermal insulation product forms comprising a plurality of the inorganic fibers, methods of preparing the inorganic fiber and of thermally insulating articles using thermal insulation prepared from a plurality of the inorganic fibers.
