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-alumi...
1. A process for producing glass fibers from raw glass batch in a refractory lined glass melter, the process comprising the steps of: charging raw glass batch to the melting zone of the glass melter, the glass batch comprising: about 60.5 to about 70.5 weight percent SiO2;about 10 to about 24.5 weight percent Al2O3;about 11.96 to about 20.0 weight percent RO, where RO equals the sum of MgO, CaO, SrO and BaO in the batch composition, wherein the amount of MgO in said alkaline earth oxide comprises at least 5 weight percent of said batch composition and th...
