    摘要： A process for producing glass tubes is provided that includes: applying a glass melt onto the outer surface of a rotating cylindrical shaping body to form thereon a hollow glass melt body; and withdrawing the hollow glass melt body over the shaping body toward a front end for forming a glass tube; wherein the shaping body is coated with platinum or a platinum alloy in regions that are in contact with the glass melt. The glass melt has a composition in wt.-% of: SiO2 71.0 to 77.0; B2O3 9.0 to 12.0; Na2O 5.5 to 8.0; K2O 0.0 to 2.0; Al2O3 6.5 to 8.0; CaO 0.0 to 1.5; BaO 0.0 to 2.0; Li2O 0.0 to 0.5; ZrO2 0.0 to 5.0. The glass composition provides enhanced devitrification characteristics so that glass tubes can be drawn using a Danner mandrel that is coated with platinum or a platinum alloy.

    摘要： Borosilicate glasses, preferably for use in the pharmaceutical sector, are provided. The borosilicate glasses are outstandingly suitable for the use as pharmaceutical primary packaging, such as phials or ampoules, since the aqueous or water-containing medicaments kept in the containers do not attack the glass significantly, and so the glass releases no, or only few, ions. The borosilicate glasses have the following composition in % by weight or consist thereof: SiO271-77; B2O39-12; Al2O35.5-8; Na2O6-8; K2O0.1-0.9; Li2O0-0.3; CaO0-1.5; BaO0-1; F0-0.3; Cl-0-0.3; and MgO + CaO + BaO + SrO 0-2.

    摘要翻译： 提供优选用于制药领域的硼硅酸盐玻璃。 硼硅酸盐玻璃非常适合用作药物初级包装，例如药瓶或安瓿，因为保持在容器中的含水或含水药物不会显着地侵蚀玻璃，因此玻璃不会释放出或仅少量的， 离子。 硼硅酸盐玻璃具有以重量％计的以下组成或其组成：SiO 2 71-77; B2O3 9-12; Al2O3 5.5-8; Na2O 6-8; K2O 0.1-0.9; Li2O 0-0.3; CaO 0-1.5; BaO 0-1; F 0-0.3; Cl- 0-0.3; 和MgO + CaO + BaO + SrO 0-2。

    摘要： A chemically temperable borosilicate glass article has a low boron content and a corresponding Na2O content. The articles have good diffusivities and hydrolytical resistance values. When chemically tempered, the borosilicate glass article exhibits a compressive stress CS >400 MPa and a penetration depth DoL >20 μm. A pharmaceutical primary packaging including the borosilicate glass article is also disclosed.

    摘要： A method for producing a glass article having high hydrolytic resistance is provided. A glass tube consisting of borosilicate glass and having an Al2O3 content of less than 1 weight-%, a ZrO2 content of 2-12 weight-%, and a glass transition temperature Tg is reshaped into a glass article and is subsequently subjected to a thermal post-treatment. To reduce the alkali release of the glass article, the glass article is subjected to a treatment temperature of TB≥Tg+5° K over a treatment time of tB≥5 min and is subsequently cooled during the thermal post-treatment.
