Glaszusammensetzung und Verfahren zur Herstellung hochtemperaturbeständiger Glasfasern

摘要

The invention relates to Al2O3-containing, high temperature resistant glass sliver based on silicic acid, having a highly textile, cotton-like and voluminous character. The invention also relates to glass staple fiber products from said glass sliver and their use. The textile character and high temperature resistance are obtained in particular by selective acid extraction. The composition of the inventive glass sliver comprises in particular SiO2, as main component, and 1-5 weight% Al2O3, as subsidiary components.
