INORGANIC FIBER COMPOSITION CONSISTING ESSENTIALLY OF Al 2?O 3?, MgO, CaO AND SiO 2?

摘要

The compositions of inorganic fibers described above consist essentially of SiO2, CaO, about 0.1-30% by weight of MgO, and 0-10% by weight of Al2O3. The fibers of this invention are suitable for thermal insulation in continuous operating temperatures between 1370 ° F and 1500 ° F and are intended particularly to covers and insulating mats for stoves and catalytic converters of motor vehicles.
