Structural Role of Nitrogen in Phosphate Glasses
Abstract
In phosphorus oxynitride glasses, doubly and triply coordinated nitrogen ions replace the bridging and nonbridging oxygen ions in the PO4 tetrahedra, thereby increasing the crosslinking between the P(O, N)4 groups. For the alkali metaphosphate composition, this process continues until all of the PO4 groups are converted to PO2N2 groups which corresponds to the composition RPO1.75N0.83 and a maximum nitrogen content of 18.12 at .%.
