In addition, a broad absorption peak appears near 1080cm-1, with 10%SiO2 being the broadest (Figure 4A), which corresponds to the antisymmetric stretching vibration peak of the Si-O bond.
In addition, a very wide absorption peak appears near 1080cm-1, with a width of 10% SiO2 (Figure 4A), corresponding to the opposing telescopic vibration peak of the Si-O key.
In addition, there is a wide absorption peak near 1080cm-1, with the widest absorption peak of 10% SiO2 (FIG. 4A), corresponding to the antisymmetric stretching vibration peak of Si-O bond.<br>
