    Abstract: A method for producing glass vials, in particular pharmaceutical vials or pharmaceutical ampoules, from a glass tube is provided, the method including the following steps: (a) rotating the glass tube about a longitudinal axis thereof; (b) locally heating the glass tube from one side by means of at least one burner to at least the softening temperature of the glass; (c) reducing the diameter by pressing at least one forming body laterally against the heated region; and (d) separating the glass tube by means of a burner. A glass vial produced in such a way releases a reduced amount of alkali in accordance with ISO 4802 and has a decreased delamination tendency. Furthermore, in the hot-formed peripheral region, the alkali content is only slightly reduced when compared with the alkali content in the glass interior.

    Abstract: 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.

    Abstract translation: 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。
