Glass fiber for high temperature insulation

摘要

A glass composition is provided for the production of high temperature glass fibers with oxides comprising 1% to 15% Fe₂O₃+FeO as a fluidizer to lower liquidous temperature and the fiberizing temperature of a mix of high temperature oxides. The glass composition has therein an appropriate content of high temperature oxides to produce glass fiber with high temperature limits and high burn-through properties.
