Saline soluble inorganic fibers

摘要

A method for insulating an article requiring resistance against repeated exposure to temperatures exceeding 900° C. uses saline soluble, non-metallic, amorphous, inorganic oxide, refractory fibrous materials as thermal insulation. The compositions that can be used for that purpose include vitreous fibers based on SiO₂, CaO, M_gO, and optionally, A₂O₃.
