Abstract

Na-Li-Si-Al-P-O-N glasses have been prepared by nitridation of a pre-synthesized Na ₂O-Li ₂O-SiO ₂-P ₂O ₅-Al ₂O ₃ glass under anhydrous ammonia. Nitrogen for oxygen substitution increases the network connectivity leading to increases in microhardness and glass transition temperature. Raman and ³¹P MAS-NMR spectroscopy indicate sequential nitridation reactions forming PO ₃N and PO ₂N ₂ species. The data collected so far show no evidence of N/O substitutions in the silicate sub-network.
