摘要:
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 TiO2, 0.25 wt %-2.5 wt % of CeO2 and 0.25 wt %-3.0 wt % of Y2O3, 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.
