Title:
GLASS COMPOSITION FOR GLASS FIBER, GLASS FIBER, AND METHOD FOR PRODUCING GLASS FIBER
Document Type and Number:
WIPO Patent Application WO/2016/093212
Kind Code:
A1
Abstract:
Provided is an alkali-resistant glass composition for a glass fiber, said composition having good productivity since the difference between the spinning temperature and liquid phase temperature of the glass is large, and having devitrification properties that do not easily change due to compositional variation. The present invention is characterized by containing, as a glass composition, by mass% in terms of oxides, 50-65% of SiO2, 0-5% of Al2O3, 0.3-10% of CaO, 10-20% of Na2O, 0.6-5% of K2O, 7.3-10% of TiO2, and 17-20% of ZrO2.
