INORGANIC FIBER COMPOSITION CONSISTING ESSENTIALLY OF AL2O3, MGO, CAO AND SIO2

摘要

Inorganic fiber compositions consisting essentially of SiO2,CaO, about 0.1-30 wt % MgO, and 0-10 wt % Al2O3. The fibers of this invention are suitable for thermal insulation at continuous service temperatures from 1370 DEG F to 1500 DEG F and find particular use as insulating mats and blankets for furnaces, kilns, and automobile catalytic converters.
