    摘要: Refractory fibers comprising a homogeneous mixture of 60 to 95 weight percent amorphous alumina and 40 to 5 weight percent amorphous phosphorus pentoxide. The fibers optionally can contain chloride, and up to 20 weight percent carbon derived from the alumina precursor material. Other organic residues can be present. The fibers are useful in the manufacture of fireproof consumer fabrics as well as reinforcement or polymeric composites.
