INORGANIC FIBER WITH IMPROVED SHRINKAGE AND STRENGTH

摘要

An inorganic fiber containing silica and magnesia as the major fiber components which further includes intended lithium oxide and strontium oxide additions to improve the thermal stability of the fiber. The inorganic fiber exhibits good thermal performance at 1260°C and greater, retains mechanical integrity after exposure to the use temperature, and exhibits low biopersistence in physiological fluids. Also provided are thermal insulation product forms, methods of preparing the inorganic fiber and of thermally insulating articles using thermal insulation prepared from a plurality of the inorganic fibers.
