Transparent, smooth, fracture resistant, discreet, refractory oxide fibers of homogeneous chemical composition comprising 96 to 100 weight percent of a mixture or chemical combination of 67 to 77 parts by weight alumina and 23 to 33 parts by weight silica, said fibers having a predominant polycrysta

Transparent, smooth, fracture resistant, discreet, refractory oxide fibers of homogeneous chemical composition comprising 96 to 100 weight percent of a mixture or chemical combination of 67 to 77 parts by weight alumina and 23 to 33 parts by weight silica, said fibers having a predominant polycrystalline phase of mullite, transitional alumina, or a mixture of both, said refractory fibers being made by fiberizing a viscous liquid of oxide precursors comprising a silica sol and a water dispersible alumina sol or water soluble or dispersible organic aluminum salt, and drying, collecting, and calcining the resulting green fibers.
