Abstract
Disclosed are glass compositions containing Beryllia in addition to various proportions of Silica, Alumina, Calcium, Magnesia, Sodium, Potassium, Iron, Titania, Zirconia, Manganese and/or Phosphorous. Fibers were produced from the disclosed compositions using standard glass processing equipment. These fibers yielded high temperature fibers having low density, high strength, high modulus, excellent glass surfaces requiring very little bonding material to hold the fibers together. Bio solubility is preferably promoted by ensuring that only trace quantities of alumina are present. Fibers having those properties are particularly suitable for producing high temperature glass fiber insulation for use in aircraft and other vehicles.
