Abstract:
An electronic-grade glass fiber composition includes the following components with corresponding amounts by weight percentages 51.0-57.5% SiO2, 11.0-17.0% Al2O3, >4.5% and ≤6.4% B2O3, 19.5-24.8% CaO, 0.1-1.9% MgO, 0.05-1.2% R2O=Na2O+K2O+Li2O, 0.05-0.8% Fe2O3, 0.01-1.0% TiO2, and 0.01-1.0% F2. A weight percentage ratio C1=SiO2/B2O3 is 8.1-12.7, a weight percentage ratio C2=B2O3/(R2O+MgO) is 1.7-6.3, and a total weight percentage of the above components is greater than or equal to 99%.
