    Abstract: The present invention relates generally to glass compositions incorporating rare earth oxides (RE2O3). In one embodiment, a glass composition suitable for fiber forming comprises 51-70 wt. % SiO2, 12.5-22 wt. % Al2O3, 0-20 wt. % CaO, 0-11 wt. % MgO, 0.2-1 wt. % Fe2O3, 0.05 or greater wt. % RE2O3, and greater than 1 wt. % MnOx. In another embodiment, a glass composition suitable for fiber forming comprises 51-70 wt. % SiO2, 12.5-22 wt. % Al2O3, 0-20 wt. % CaO, 0-11 wt. % MgO, 0.2-1 wt. % Fe2O3, 0.05 or greater wt. % RE2O3, 0-4 wt. % BaO, 0-4 wt. % SrO, and 0-5.5 wt. % ZnO, wherein the sum of BaO+SrO+ZnO is greater than about 2 wt. %. In another embodiment, a glass composition suitable for fiber forming comprises 51-70 wt. % SiO2, 12.5-22 wt. % Al2O3, 0-20 wt. % CaO, 0-11 wt. % MgO, 0.2-1 wt. % Fe2O3, 0.05 or greater wt. % RE2O3, and from greater than 0 to 2.5 wt. % Cu2O. In another embodiment, a glass composition suitable for fiber forming comprises 51-70 wt. % SiO2, 12.5-22 wt. % Al2O3, 0-20 wt. % CaO, 0-12.5 wt. % MgO, 0.2-1 wt. % Fe2O3, 0.05 or greater wt. % RE2O3, and at least one additional feature selected from the group consisting of: La2O3 is present in an amount greater than about 2 weight percent, CaO is present in an amount less than about 2 weight percent, a MgO/CaO ratio less than about 1, and a SiO2/Al2O3 ratio greater than about 4. The glass compositions can be used to form glass fibers which can be incorporated into a variety of other fiber glass products (e.g., strands, rovings, fabrics, etc.) and incorporated into various composites.

    Abstract: Glass compositions suitable for fiber forming having low levels of Li2O and glass fibers having high-modulus are disclosed. The glass composition may include SiO2 from about 59 to about 63 weight percent, Al2O3 from about 13.7 to about 16 weight percent, CaO from about 14 to about 16.5 weight percent, MgO from about 6 to about 8.5 weight percent, Fe2O3 less than 1 weight percent, and TiO2 less than 1 weight percent. In some cases, the composition may be substantially free of Li2O. In some cases, the composition may include Li2O up to 0.5 weight percent. In some cases, RE2O3 may be present in the composition in an amount up to 1.5 weight percent. The glass compositions can be used to form glass fibers which can be incorporated into a variety of other fiber glass products (e.g., strands, rovings, fabrics, etc.) and incorporated into various composites.
