TY - GEN N1 - Optica Applicata, Vol. 37, 2007, nr 1-2, s. 41-50 N2 - Structural changes in sodium-calcium-silicate glass after adding Si3N4 (silicon nitride) were investigated. The research included the use of the atom radial decomposition functions (RDF) and infrared spectroscopy. The results of RDF analysis and infrared absorptive spectroscopy have revealed the existence of oxygen-silicone tetrahedra. Moreover, the most probable nitrogen location in oxide-nitrogen glass has been confirmed.
