Abstract (AI)
The infrared absorption spectra of sodium silicate glasses of molar composition Na 2 O·xSiO 2 (where = 5, 4, 3, and 2) were determined with unpolarized radiation in the 4 to 30μ region. The glass spectra showed a definite similarity to the spectra of α‐quartz, with lattice vibrational bands around 1066,786, and 464 cm −1 . As x decreased, some bands shifted toward lower frequencies indicating a decrease in the force constant. No new frequencies were found in the silicate glasses which did not have counterparts in α‐quartz.
Key Findings
1
Decreasing x (increasing Na2O content) causes some bands to shift to lower frequencies, indicating decreased force constants.
2
Glass spectra show definite similarity to α‑quartz spectra, with lattice vibrational bands near 1066, 786, and 464 cm⁻¹.
3
Infrared absorption spectra of Na2O·xSiO2 glasses were measured from 4 to 30 μm using unpolarized radiation.
4
No new infrared frequencies were observed in the sodium silicate glasses that did not have counterparts in α‑quartz.
