Abstract: A glass, a glass article made of the glass as well as uses and production methods are disclosed. The glass constituents are selected such that excellent scratch resistance and impact strength are provided. The glass has a composition characterized by the following constituent phases: 15-60 mol % reedmergnerite; 20-60 mol % albite; 0-20 mol % nepheline; 0-20 mol % orthoclase; 0-20 mol % parakeldyshite; 0-20 mol % narsarsukite; 0.1-30 mol % disodium zinc silicate; 0-4 mol % diboron trioxide; 0-20 mol % cordierite; and 0-20 mol % danburite. A quotient of a coefficient of thermal expansion of the glass multiplied by 1000 (in ppm/K) and the product of a pH value and a removal rate in alkaline environment (in mg/(dm23h)) according to ISO 695 is at least 8 and the removal rate in alkaline environment according to ISO 695 is at most 115 mg/(dm23h).

Abstract: A glass is described, a glass article made of the glass as well as uses and production methods. The glass constituents are selected such that it results in excellent chemical stability and ion ex-changeability. The glass has a composition characterized by the following glass constituent phases: 0-35 mol % reedmergnerite; 10-60 mol % albite; 3.5-25 mol % orthoclase; 0-40 mol % natrosilite; 0-20 mol % parakeldyshite; 0-20 mol % narsarsukite; 0-35 mol % disodium zinc silicate; 0-35 mol % silicon dioxide; 0-30 mol % cordierite; and 0-20 mol % danburite. A quotient of a coefficient of thermal expansion of the glass multiplied by 1000 (in ppm/K) and the product of a pH value and a removal rate in alkaline environment (in mg/(dm23h)) according to ISO 695 is at least 9.25.

Abstract: The present invention relates to glasses, such as e.g. thin or thinnest glasses, but also to glasses for the production of tubular glass, carpules and syringes as well as other pharmaceutical vessels. The glasses are characterized by a high chemical prestressability (tem-perability) with very well alkali, hydrolytic and/or acid resistance as well as an advantageous coefficient of thermal expansion. The glass has a composition characterized by the following constituent phases: 0-60 mol % reedmergnerite; 20-60 mol % albite; 0-30 mol % orthoclase; 0-20 mol % natrosilite; 0-20 mol % sodium metasilicate; 0-20 mol % parakeldyshite; 0-20 mol % narsarsukite; 0-20 mol % disodium zinc silicate; 0-21 mol % cordierite; and 0-20 mol % danburite. A quotient of a coefficient of thermal expansion of the glass multiplied by 1000 (in ppm/K) and the product of a pH value and a removal rate in alkaline environment (in mg/(dm23h)) according to ISO 695 is at least 9.0.

Abstract: The invention relates to a photonic crystal fiber, in particular single-mode fiber, for the transmission of electromagnetic radiation in the IR wavelength range of >1 μm, in particular in the wavelength range from 1 μm to 20 μm, preferably from 9 μm to 12 μm, having a light-conducting hollow core, in particular a hollow core having a diameter D, and a plurality of hollow bodies, in particular hollow tubes composed of a chalcogenide glass, arranged around the light-conducting hollow core. The hollow bodies (10, 20) are arranged in such a way that the diameter D of the light-conducting hollow core is greater than the shortest wavelength to be transmitted, preferably at least 20 μm, preferably at least 50 μm, particularly preferably at least 100 μm, preferably in the range from 100 μm to 500 μm, in particular in the range from 150 μm to 350 μm, and the damping for the transmission of electromagnetic radiation is
