Embodiment 1

[0056] This example is used to illustrate that the neutral borosilicate glass composition according to the present invention is prepared according to the formula and process parameters in Table 1, and the method as described below.

[0057] The method for preparing neutral borosilicate glass comprises the following steps:

[0058] Weigh the components of the glass composition shown in Table 1, mix them uniformly to obtain a mixture, put the mixture into a melting kiln at 1550°C and melt for 350 minutes to obtain molten glass, and then carry out clarification treatment on the molten glass , by adjusting the temperature to 1580°C, discharging air bubbles to obtain molten glass, and then forming the obtained molten glass by Danner method, cutting the formed glass into a predetermined length (1500mm), and annealing at 560°C for 15 minutes to obtain a glass sample .

[0059] In the absence of special instructions, the remaining examples and comparative examples are carried out usi...

Abstract

The invention relates to the field of medical glass packing materials, and discloses a neutral borosilicate glass composition, neutral borosilicate glass and a preparation method and application thereof. The neutral borosilicate glass composition contains SiO2, Al2O3, B2O3, Na2O, K2O, Li2O, CeO2, chloride, ZrO2, MgO and CaO which are independently stored or stored in a mixed mode of two or more of SiO2, Al2O3, B2O3, Na2O, K2O, Li2O, CeO2, chloride, ZrO2, MgO and CaO. The neutral borosilicate glass prepared from the neutral borosilicate glass composition disclosed by the invention not only has high chemical stability and excellent hydrolysis resistance, but also has low crystallization tendency and lower melting and softening temperature, is easy to process and has good processing performance.

Description

technical field [0001] The invention relates to the field of medical glass packaging materials, in particular to a neutral borosilicate glass composition, a neutral borosilicate glass and a preparation method and application thereof. Background technique [0002] In the field of medicine, glass is widely used as a packaging material. Its special material properties, such as high transparency, mechanical resistance, low permeability and high chemical stability, are critical to maintaining the quality and efficacy of medicinal substances. . [0003] Especially for medium borosilicate glass used in pharmaceutical containers such as vials and ampoules, the following characteristics are required: [0004] (1) The ingredients in the filled liquid medicine do not react with the ingredients in the glass; [0005] (2) High chemical durability and hydrolysis resistance to prevent contamination of the filled liquid medicine; [0006] (3) The coefficient of thermal expansion is low, ...
