What is it about?
Substitution of oxygen by N in the structure of Ca-Mg -Al-silicate glasses results in substantial increases in Young's modulus and microhardness whereas F has no significant effect on these properties. F reduces the glass-transition temperature and the softening point of the glasses whereas N increases these thermal properties. The paper discusses these changes in relation to glass structure.
