Abstract (en)

[origin: WO9818618A1] Mineral fiber compositions are disclosed which, in a first embodiment, include the following components, indicated in weight percents: about 54 to about 70 percent SiO2, about 0 to about 4 percent Al2O3, about 0 to about 6 percent Na2O, about 0 to about 6 percent K2O, about 0 to about 6 percent MgO, about 10 to about 28 percent CaO, about 6 to about 17 percent total iron as FeO, and about 0 to about 5 percent TiO2, wherein the total weight percent of SiO2 and Al2O3 ranges from about 56 percent to about 72 percent, the total weight percent of MgO and CaO ranges from about 12 percent to about 28 percent, the total weight percent of Na2O and K2O does not exceed 6 percent, and the total weight percent of all components, including trace elements, if any, is 100 percent. In a second embodiment, the compositions include the following components, indicated in weight percents: about 50 to about 68 percent SiO2, about 0 to about 4 percent Al2O3, about 0 to about 6 percent K2O, about 0 to about 6 percent Na2O, about 0 to about 10 percent MgO, about 10 to about 28 percent CaO, about 6 to about 16 percent total iron as FeO, about 0 to about 5 percent TiO2, and about 0.5 to about 12 percent ZrO2, wherein the total weight of Na2O and K2O does not exceed 6 percent and the total weight of all components, including trace elements, if any, is 100 percent.
