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 production of glass fibers is substantially reduced in comparison with the cost of fibers produced using a platinum-lined melting furnace. High strength composite articles including the high strength glass fibers are also disclosed.
A process for producing glass fibers from raw glass batch in a refractory-lined glass melter, the process comprising the steps of:
A process for producing glass from raw glass-forming material in a refractory lined glass melter, the glass melter having a roof, a bottom and side walls, defining an elongated channel having a melting zone and a downstream refining zone, the process comprising the steps of:
