优选用于医药领域的具有改良的抗水解性的硼硅玻璃
摘要：
本发明涉及优选用于医药领域的具有改良的抗水解性的硼硅玻璃。一种硼硅玻璃，尤其是用于医药领域的硼硅玻璃，其包含以重量％为单位的以下组成。本发明的硼硅玻璃特别适合用作药物初级包装，例如小瓶或安瓿，因为保存在容器中的水性或含水的药用物质不会明显地侵入玻璃，从而使本发明的硼硅玻璃不会或仅很少地释出离子。
摘要（英）：

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: SiO2 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; and MgO + CaO + BaO + SrO 0-2.
