Glass compositions, fibers and methods of making same

摘要: This disclosure relates to fiberizable glass compositions, fibers and the method of making textile which are boron fluorine free. Boron have now been recognized as potential pollutants in manufacture glasses following eliminates these by substituting TiO2, MgO ZnO basic three component composition SiO2, Al2O3 CaO. The preferred consists essentially of, weight, 54.5 60% 9 14.5%Al2O3, 17 24% CaO, 2 4% 1.5 1 5.5% RO, wherein RO is an oxide selected from group consisting ZnO, SrO BaO, calculated ZnO.
