Improved Impact Resistance in Soda‐Lime‐Silica Glasses Through Zinc Oxide Substitutions

Abstract

Several soda‐lime‐silica glasses were melted in which up to 8.52 wt% zinc oxide was substituted for calcium and magnesium oxide. Sonic Young's modulus and Charpy impact resistance measurements were made. The results indicated that an increase of 8.52 wt % zinc oxide reduced the Young's modulus by 9.0% and increased the impact resistance of the soda‐lime‐silica glass by 4.1%.

“…Materials which have higher value of Young's modulus imply that that particular material is more stiffer and this Young's modulus is also affected by the dimensionality and connectivity of the system [33]. Not only that, samples that have higher value of Young's modulus can endure more stress compared to samples which possess lower Young's modulus and Figure 5 shows that as the amount of ZnO in the samples increases, Young's modulus of the samples decreases which indicates the increase in number of NBOs [34]. Decrease in the NBOs further links to the decrease in connectivity of the samples network which is caused by the decrease in Young's modulus.…”

“…Decrease in the NBOs further links to the decrease in connectivity of the samples network which is caused by the decrease in Young's modulus. Lower Young's modulus as ZnO increases shows that the ZnO-SiO 2 samples can reduce the speed of impacting mass thus causing a smaller stress compared to samples which have higher Young's modulus [34]. Results of Young's modulus can indicate that the samples can bear small stress acting against it even though its structure is less rigid and the decrease in Young's modulus indicates that the samples can work well with strain.…”
