In particular, the effect of the ammonia gas flow rate during nitridation was studied. The effective nitrogen concentration (Neff) in the obtained powder, analyzed by X-ray fluorescence, increased with an increase in the flow rate, and the results of X-ray photoemission, nuclear magnetic resonance, and Fourier transform infrared (FT-IR) spectroscopy measurements indicated that the population of Si–N bonds increased with an increase in Neff. However, the presence of hydrogen-terminated structures, such as –NHn, in the powder with high Neff was confirmed by FT-IR measurements. The presence of hydrogen-terminated structures, such as –Si–NHn, and the thermal stability of these hydrogen-related structures were further investigated by thermal analyses, including thermal desorption measurements, which suggested that hydrogen-terminated structures can be easily formed during the nitridation of the gel and that the formation of hydrogen-terminated structures inhibits the polymerization of the glass structures.\r\nReferences (73)\r\n\r\n 1) K.
