“… The increase in Young's modulus of 60Si:20RE:20Mg oxynitride glasses correlates well with increase in cationic field strength (CN=6) but only if CN is assumed to be 8 for Yb and Sc (arrows show shift from CN=6 to CN=8 for Yb and Sc). 39,75 …”

The silicon oxynitride glasses take advantage of nitrogen bonding to attain high elastic modulus, increased softening temperatures and viscosities, greater slow crack growth resistance, and modest gains in fracture resistance. Of the oxynitride glasses, the Si–Y–Al‐based oxynitride glasses have been most extensively studied and a degree of success has been achieved in understanding how changes in glass composition affect structural parameters and their relationship with properties. More recent studies have focused on the Si–RE–Me oxynitride glasses, where Me is primarily Al or Mg and rare earth (RE) includes most of the lanthanide series elements. These glasses possess a range of elastic, thermal, mechanical, and optical properties, which can be correlated with the strength of the RE bond in terms of the cationic field strength. However, such correlations require knowledge of not only the RE valence state but also its coordination with the anions. Herein, the current state‐of‐the‐art understanding of the properties and structural parameters of oxynitride glasses and their interrelationships are reviewed.

“…A contradictory explanation can be recommended for the effect of barium and titanium oxides, i.e. they increase the numbers of non-bridging oxygen in the glasses and hereby decrease the viscosity of the glasses [18][19][20][21][22][23]. To investigate the crystallization procedure and development of the crystalline phases in the prepared glasses, the samples were heat treated at different temperatures for 3 h. Based on the XRD results, apatite and mullite were precipitated in the glasses after the mentioned heat treatment and there was not any footprint of other crystalline compounds, such as TiO 2 and ZrO 2 , in the XRD patterns, meaning that they did not act as a nucleation agent in the glasses.…”

“…Oxynitride glasses are derivatives of oxide glasses, where oxygen is partly substituted by nitrogen. This substitution can improve the mechanical property and chemical stability [7][8][9][10]. These improvements are attributed to the higher packing density of atoms, lower polarization degree of the Si-N bond in comparison to the Si-O bond, and denser cross-linkage in the glass network [9].…”
