Abstract: A composition for producing a glass fiber, including the following components with corresponding percentage amounts by weight: SiO2: 57.4-60.9%; Al2O3: greater than 17% and less than or equal to 19.8%; MgO: greater than 9% and less than or equal to 12.8%; CaO: 6.4-11.8%; SrO: 0-1.6%; Na2O+K2O: 0.1-1.1%; Fe2O3: 0.05-1%; TiO2: lower than 0.8%; and SiO2+Al2O3: lower than or equal to 79.4%. The total weight percentage of the above components in the composition is greater than 99%. The weight percentage ratio of Al2O3+MgO to SiO2 is between 0.43 and 0.56, and the weight percentage ratio of CaO+MgO to SiO2+Al2O3 is greater than 0.205. The composition can significantly increase the glass modulus, effectively reduce the glass crystallization rate, secure a desirable temperature range (ΔT) for fiber formation and enhance the refinement of molten glass, thus making it particularly suitable for high performance glass fiber production with refractory-lined furnaces.

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%.
