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.

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 glass has a maximum crystallization rate (KGmax) of at most 0.20 μm/min in a temperature range of 700° C. to 1250° C. and a hydrolytic stability according to a hydrolytic class 1 HGA1 according to ISO 720:1985. In the case of a sample thickness of 2 mm of the glass, a ratio of a minimum transmittance in a wavelength range of 850 nm to 950 nm to a maximum transmittance in a wavelength range of 250 nm to 700 nm is in a range of 1.9:1 to 15:1.
