Abstract: One aspect relates to a light guide comprising a jacket and one or more cores, wherein the jacket surrounds the cores. Each core has a refractive index profile perpendicular to the maximum extension of the core, wherein at least one refractive index nK of each refractive index profile is greater than the refractive index nM1 of the jacket. The jacket is made of silicon dioxide and has an OH content of less than 10 ppm, a chlorine content of less than 60 ppm, and an aluminium content of less than 200 ppb. One aspect also relates to a silicon dioxide granulate I, characterized by a chlorine content of less than 200 ppm and an aluminium content of less than 200 ppb, in each case based on the total weight of the silicon dioxide granulate I.

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.

Abstract: A high silica glass composition comprising about 92 to about 99.9999 wt. % SiO2 and from about 0.0001 to about 8 wt. % of at least one dopant selected from Al2O3, CeO2, TiO2, La2O3, Y2O3, Nd2O3, other rare earth oxides, and mixtures of two or more thereof. The glass composition has a working point temperature ranging from 600 to 2,000° C. These compositions exhibit stability similar to pure fused quartz, but have a moderate working temperature to enable cost effective fabrication of pharmaceutical packages. The glass is particularly useful as a packaging material for pharmaceutical applications, such as, for example pre-filled syringes, ampoules and vials.
