Abstract: A method of producing flint glass using submerged combustion melting involves introducing a vitrifiable feed material into a glass melt contained within a submerged combustion melter. The vitrifiable feed material is formulated to provide the glass melt with a glass chemical composition suitable for producing flint glass articles. To that end, the glass melt comprises a total iron content expressed as Fe2O3 in an amount ranging from 0.04 wt % to 0.06 wt % and also has a redox ratio that ranges from 0.1 to 0.4, and the vitrifiable feed material further includes between 0.008 wt % and 0.016 wt % of selenium or between 0.1 wt % and 0.2 wt % of manganese oxide in order to achieve an appropriate content of selenium or manganese oxide in the glass melt.

Abstract: The present invention provides a glass fiber composition, glass fiber and composite material therefrom. The glass fiber composition comprises the following components expressed as percentage by weight: 58-63% SiO2, 13-17% Al2O3, 6-11.8% CaO, 7-11% MgO, 3.05-8% SrO, 0.1-2% Na2O+K2O+Li2O, 0.1-1% Fe2O3, 0-1% CeO2 and 0-2% TiO2, wherein a weight percentage ratio C1=(MgO+SrO)/CaO is greater than 1. Said composition greatly improves the refractive index of glass, significantly shields against harmful rays for humans and further reduces glass crystallization risk and production costs, thereby making it more suitable for large-scale production with refractory-lined furnaces.

Alternatively, the core region is doped with one or more viscosity-reducing dopants in respective amounts that are configured such that the fiber has a residual axial compressive stress with a stress magnitude of more than 20 MPa and a stress radial extent between 2 and 7 times the core radius.According to another aspect of the invention a majority of the optical propagation through the fiber is supported by an identified group of fiber regions comprising the core region and one or more adjacent cladding regions. The fiber regions are doped with one or more viscosity-reducing dopants in respective amounts and radial positions that are configured to achieve viscosity matching among the fiber regions in the identified group.

Preferably the glass has a viscosity coefficient at 1215° C. of at least 1011.5 Pa·s; and a Cu ion diffusion coefficient of not larger than 1×10−10 cm2/sec in a depth range of greater than 20 μm up to 100 μm, from the surface, when leaving to stand at 1050° C. in air for 24 hours. The glass is made by cristobalitizing powdery silica raw material; then, fusing the cristobalitized silica material in a non-reducing atmosphere. The glass exhibits a high transmittance of ultraviolet, visible and infrared rays, has high purity and heat resistance, and exhibits a reduced diffusion rate of metal impurities, therefore, it is suitable for various optical goods, semiconductor-production apparatus members, and liquid crystal display production apparatus members.
