Silicon-oxynitride glasses were prepared in the NaSiON, NaSiON, and the NaBSiON systems by conventional melting techniques. Increasing amounts of nitrogen were substituted for oxygen to a two weight percent level of nitrogen. The Young's elastic moduli, Vicker's microhardnesses, and the fracture toughnesses were measured and observed to increase linearly with nitrogen content in each of these systems. These results are consistent with the incorporation of nitrogen into the glass structure in three-fold coordination with silicon.
