Abstract:
An electronic-grade glass fiber composition includes the following components with corresponding amounts by weight percentages: 54.2-60% SiO2, 11-17.5% Al2O3, 0.7-4.5% B2O3, 18-23.8% CaO, 1-5.5% MgO, less than or equal to 24.8% CaO+MgO, less than 1% Na2O+K2O+Li2O, 0.05-0.8% TiO2, 0.05-0.7% Fe2O3, and 0.01-1.2% F2. The weight percentage ratio C1=SiO2/(RO+R2O) is greater than or equal to 2.20, and the total weight percentage of the above components is greater than or equal to 98.5%.
