Abstract

Disclosed is a type of borosilicate glass, the composition of which, based on oxides, contains the following components by weight percentage (wt %): 2.0 wt %-5.0 wt % of TiO, 0.25 wt %-2.5 wt % of CeOand 0.25 wt %-3.0 wt % of YO, and does not contain any iron compound, such as ferric oxide. The glass has better UV resistance and alkaline resistance properties, and a better light transmission rate, and is particularly suitable for use in the field of pharmaceutical packaging materials.
