摘要：
Na-Li-Si-Al-P-O-N glasses have been prepared by nitridation of a pre-synthesized Na2O-Li2O-SiO2-P2O5-Al2O3 glass under anhydrous ammonia. Nitrogen for oxygen substitution increases the network connectivity leading to increases in microhardness and glass transition temperature. Raman and P-31 MAS-NMR spectroscopy indicate sequential nitridation reactions forming PO3N and PO2N2 species. The data collected so far show no evidence of N/O substitutions in the silicate sub-network. (C) 2012 Elsevier B.V. All rights reserved.
