Abstract

The properties and structural role of nitrogen in phosphorus oxynitride glasses are reported. Properties summarized for several compositions include the dissolution rate in water, thermal expansion coefficient, viscosity and refractive index. The bonding and coordination number of nitrogen in the glass network has been deduced from nuclear magnetic resonance, X-ray photoelectron spectroscopy and Raman spectroscopy. The existing evidence shows that nitrogen replaces oxygen in the PO4 network as doubly coordinated (=N-) and triply coordinated (> N-) N3− ions. The measured properties are consistent with these network structural features.
