| Abstract: | Oxynitride glasses begin to oxidize in air when they are heated above 800°C. The oxidation starts with bubble formation on the surface. Continued oxidation leads to a white oxide layer on the surface. Magnesia- and lithia-containing glasses formed crystalline layers, whereas soda- and baria-containing glasses formed bubbly glass layers. The lithia-, beryllia-, and magnesia-containing glasses have good oxidation resistance |
