A method of forming high strength glass fibers in a refractory-lined glass melter, products made there from and batch compositions suited for use in the method are disclosed. The glass composition for use in the method of the present invention is up to about 64-75 weight percent SiO2, 16-24 weight percent Al2O3, 8-12 weight percent MgO and 0.25-3 weight percent R2O, where R2O equals the sum of Li2O and Na2O, has a fiberizing temperature less than about 2650° F., and a ΔT of at least 80° F. By using oxide-based refractory-lined furnaces the cost of produc...
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 a refractory-lined glass melter, the glass batch comprising: 64-75 weight percent SiO2;16-24 weight percent Al2O3;8-11 weight percent MgO;1.75-3 weight percent Li2O; andno more than 2.0 weight percent CaO,heating the glass batch to form a fiberizable molten glass having a fiberizing temperature of less than about 2600° F.; andfiberizing said molten glass to produce glass fibe...
