ABSTRACT:
A method of forming high strength glass fibers in a refractory lined glass melter is disclosed. The refractory lined melter is suited to the batch compositions disclosed for the formation high modulus, and high-strength glass fibers. The glass composition for use in the method of the present invention is up to about 70.5 Weight % SiO2, 24.5 weight % Al2O3, 22 weight % alkaline earth oxides and may include small amounts of alkali metal oxides and ZrO2. Oxide based refractories included alumina, chromic oxide, silica, alumina-silica, zircon, zirconia-alumina-silica and combinations thereof. By using oxide based refractory lined furnaces the cost of production of glass fibers is substantially reduced in comparison with the cost of fibers using a platinum lined melting furnace. Fibers formed by the present invention are also disclosed.
