    • The lead- and cadmium-free glass composition for glazing, enameling and decorating glass or glass-ceramic articles contains high quartz and/or keatite solid solution crystals as principal crystalline phases after crystallization and a low thermal expansion coefficient of less than 2.times.10.sup.-6 /K at temperatures between 20 and 700.degree. C. This glass composition contains Li.sub.2 O, 0 to 5% by weight; Na.sub.2 O, 0 to 5% by weight; K.sub.2 O, less than 2% by weight; MgO, 0 to 3% by weight; CaO, 0 to 4% by weight; SrO, 0 to 4% by weight; BaO, 0 to 4% by weight; ZnO, 0 to 4% by weight; B.sub.2 O.sub.3, 15 to 27% by weight; Al.sub.2 O.sub.3, 10 to 20% by weight; SiO.sub.2, 43 to 58% by weight; TiO.sub.2, 0 to 3% by weight and ZrO.sub.2, 0 to 4% by weight, Sb.sub.2 O.sub.3, 0 to 2% by weight; F, 0 to 3% by weight in exchange for oxygen and up to 30% by weight of at least one inorganic pigment resistant to a burning-in temperature on the glass or the glass-ceramics. The sum total amount of Li.sub.2 O, Na.sub.2 O and K.sub.2 O must be from 1 to 10% by weight. An average bending tensile strength of a glass-ceramic or glass article completely coated with the glass composition after burning-in is greater than 30 MPa.

    • The glass container stores and preserves pharmaceutical or diagnostic solutions for medicinal purposes. So that the container is free of silicones and other residues, it is provided with an amorphous, transparent anti-adherent coating (4) over its entire interior surface from its bottom over the wall (3) to the closure device (2). This anti-adherent coating (4) is free of heavy metals, free of silicones, is stable after autoclaving at about 120° C. for about 20 min or hot air sterilization for 30 min at 300° C., has a contact angle for wetting with water of ≧80°, contains silicon, oxygen, carbon, fluorine and hydrogen and is deposited by a PECVD method, especially a PICVD method. If the coating contains less than 0.1% by weight fluorine, then it contains greater than or equal to 10% by weight carbon, but if it contains greater than or equal to 0.1% fluorine then it contains greater than or equal to 5% by weight carbon.
    • 玻璃容器储存并保存用于药用目的的药物或诊断溶液。 为了使容器不含有机硅和其他残留物,在其整个内表面上从其底部(3)到封闭装置(2)的底部提供无定形透明的抗粘附涂层(4)。 这种抗粘附涂层(4)不含重金属,不含硅氧烷,在约120℃下高压灭菌约20分钟或在300℃热空气灭菌30分钟后是稳定的,具有接触角 用> = 80°的水润湿,含有硅,氧,碳,氟和氢,并通过PECVD法,特别是PICVD法沉积。 如果涂层含有少于0.1重量%的氟,则其含有大于或等于10重量%的碳,但如果其含有大于或等于0.1%的氟,则其含有大于或等于5重量% 碳。
