Abstract:
Disclosed herein are delamination resistant glass pharmaceutical containers which may include an aluminosilicate glass having a Class HGA 1 hydrolytic resistance when tested according to ISO 720-1985 testing standard. The glass containers may also have a compressive stress layer with a depth of layer of greater than 25 μm. A surface compressive stress of the glass containers may be greater than or equal to 350 MPa. The delamination resistant glass pharmaceutical containers may be ion exchange strengthened and the ion exchange strengthening may include treating the delamination resistant glass pharmaceutical container in a molten salt bath for a time less than or equal to 5 hours at a temperature less than or equal to 450° C.
