摘要：A method of forming high strength glass fibers in a refractory-lined glassmelter, 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 upto about -75 weight percent SiO, 16-24 weight percent AlO, 8-12 weight percent MgOand 0.25-3 weight percent RO, where RO equals the sum of LiO and NaO, has a fiberizingtemperature less than about 2650° F., and a ΔT of at least 80° F. By using oxide-basedrefractory-lined furnaces the cost of production of glass fibers is substantially reduced incomparison with the cost of fibers produced using a platinum-lined melting furnace. Highstrength composite articles including the high strength glass fibers are also disclosed.
