摘要

To analyze the impact of bubbles on the mechanical behavior of glasses, by controlling the refining time, we prepared three borosilicate glasses with the same composition and different porosity. By the analysis software integrated within the optical microscope, the diameter and number of the bubbles on the surface of three borosilicate glasses were quantified. From the hardness and crack initiation resistance (CR), we built the relationship between the porosity and the mechanical performance of these borosilicate glasses.
